ABSTRACT
This report describes briefly the uses of limestone and
dolomite and gives chemical and/or physical specifications for
each use, where known. More than 70 uses are discussed. A
bibliography gives sources of additional data.
INTRODUCTION
This report presents briefly the physical and/or chemical specifications for
various uses of limestone and dolomite, information that will aid in the maximum
utilization of the limestone and dolomite resources of Illinois. A brief discussion
of each use is given, together with general specifications that the stone must meet
to be acceptable for the indicated use. A bibliography gives sources of additional
data. Mention was found of a number of uses for which no specifications could be
located; such uses are simply listed.
This circular is an extensive revision of an earlier report (106) that has
been out of print for some years
The specifications given herein are believed to be reasonably typical, but
some may vary, depending on the preference of a user. Also, specifications may
be relaxed in certain cases to permit the use of a cheaply available stone from
deposits near at hand. In some cases it is difficult to distinguish between uses
of limestone and dolomite and those of iime. However, if stone is sold to a con-
sumer for a specific purpose, this is considered a use of limestone or dolomite
even though the stone may later be converted into lime in the process of utilization.
An attempt has been made to restrict the use of the term "limestone" to
those consolidated rocks that consist principally of the mineral calcite (calcium
carbonate). The term "dolomite" is applied, insofar as possible, to consolidated
rocks composed principally of the mineral dolomite (calcium magnesium carbonate)
However, the data in this report are drawn from diverse writers and, as not all of
them have necessarily used the terms as indicated, some laxity in exact usage
doubtless results.
Two widely used terms, high-calcium limestone and high-magnesium dolo-
mite, are commonly used industrially without exact definition. High-calcium lime-
stone is generally considered to contain more than 95 percent calcium carbonate,
but many, if not most, commercial high-calcium limestones contain more than 97
percent or 98 percent calcium carbonate. High-magnesium dolomite probably
generally contains more than 20 percent magnesium oxide or 42 percent magnesium
carbonate . The term "high purity dolomite" has been used similarly to describe
dolomites containing more than 20 percent magnesium oxide and more than 97 per-
cent magnesium carbonate and calcium carbonate together (152).
[3]
ILLINOIS STATE GEOLOGICAL SURVEY CIRCULAR 321
Table 1 shows the quantity and value of limestones and dolomites sold in
19 59 according to major uses.
ABRASIVE
According to Goudge (65), a moderately finely pulverized soft limestone
has been used as an abrasive in a process similar to sandblasting for cleaning soft
metal molds, and it is possible it may be used for buffing and cleaning of metal to
be electroplated.
ACETIC ACID
The sale of limestone for use in making acetic acid has been reported (35)
Lime isused to recover acetic acid as calcium acetate from the destructive distilla-
tion of wood (92), and the limestone may have been sold for this purpose. A high-
calcium limestone would appear to be desirable.
ACID NEUTRALIZATION
Use - Iron oxides that form on steel products shaped when the steel is
.
hot are removed by "pickling" the products in a mineral acid, commonly sulfuric
acid. The spent liquid from this operation consists essentially of ferrous sulfate
and sulfuric acid. In order to dispose of the waste liquor it may be treated with
limestone and/or lime to neutralize the acid and precipitate the iron. Limestone
also may be used to neutralize other types of acid industrial wastes.
Chemical Specifications. - The rate of reaction of pulverized limestone
seems to be approximately inversely proportional to the amount of magnesium
carbonate it contains in excess of about 2 percent (74, 75) . Dolomite or dolomitic
limestone reacts too slowly to be used in the treatment of spent pickle liquors. A
limestone containing 95 percent or more calcium carbonate is recommended (48)
Physical Specifications - Probably a variety of sizes of limestone can be
.
used, depending on the character of the acid to be neutralized and the type of
equipment employed. The use of limestone crushed to 1- to 3-mm particles in
upflow-type neutralizing systems has been suggested (48); in downflow systems
1- to 3-inch stone is commonly used (48) .
acid wastes has been described (84). The wastes resulted from the mining and
processing of ores high in iron sulfide and from the production of iron sinter and
sulfuric acid from the sulfide. The stone used had 54 percent calcium carbonate
and 37 percent magnesium carbonate. All of it passed a 35-mesh sieve and about
40 percent was retained on a 200-mesh sieve. Another grade of stone used was
95 percent through a 200-mesh sieve.
be determined by the use of the Los Angeles machine (6) . In this test a sample
of the stone, weighing between 5, 000 and 10, 000 grams and graded within certain
size limits, is placed in a cylindrical tumbling barrel having a baffle in it, togeth-
er with a charge of steel balls of specified number and weight. The cylinder is
rotated a specific number of times and thereafter the weight of stone retained on
a No. 12 sieve is determined. Percentage of wear is calculated by dividing the
weight of the material finer than the No. 12 screen by the original weight of the
sample.
Soundness - The soundness test (12) is used to determine the weather
.
dolomites are likely to fail in the tests as are those which break readily when
struck with a hammer. Many rocks containing streaks or bands of clay or shale
will fail in five cycles of the soundness test. Some chert and some limestones
having pronounced banding also fail.
Among the potentially deleterious substances that may occur naturally in
some limestone and dolomite deposits, excluding materials from overburden or
quarry floor materials, are chert, shale, and clay. The last two substances are
most likely to occur as beds or partings between layers of stone or in pockets.
According to the Illinois Division of Highways (78), maximum allowable amount of
clay lumps is 1.0 percent in fine aggregate for portland cement concrete and 0.25
percent in coarse aggregate. Soft and unsound fragments in the latter, including
chert, should not exceed 5 percent. Coarse aggregate for handrail concrete should
be "free from chert, flint, limonite, shale, and other kinds of material or substances
whose disintegration is accompanied by an increase in volume which may cause
spalling of the concrete" (81)
In aggregates for bituminous road surfaces, allowable maxima for clay lumps
range from 0.5 to 1.0 percent according to the type of construction, and for shale
from 2.0 to 4.0 percent.
Table 2 summarizes abrasion and soundness requirements for aggregates for
various purposes as specified by the Illinois Division of Highways. The American
Association of State Highway Officials (1) and the American Society for Testing
Materials (8) also have set up specifications for road aggregates involving abrasion
and soundness.

AGRICULTURAL LIMESTONE
Use - Limestone and dolomite are applied to soils to correct soil acidity,
.
add calcium and magnesium, improve soil structure, and maintain or promote con-
ditions favorable for the utilization of soil nutrients by plants and for the growth
of desirable soil organisms. Limestone and dolomite so used are variously referred
to as agricultural limestone, agstone, ag lime, or simply lime. Application of
agricultural limestone to the soil is called liming.
Chemical Specifications - The acid neutralizing value of agricultural
.
The Federal cost-sharing rate for "No. 2 limestone" is less than the cost-
sharing rate for "Standard agricultural limestone."
ALKALI
Use . Limestone is used in the ammonia soda or Solvay process for the
-
manufacture of the alkali, soda ash (Na^COJ, from either natural or artifically pro-
duced salt (NaCl) brines (13). About one (59) to one and one quarter (30) tons of
limestone are used for each ton of sodium carbonate manufactured.
Chemical Specifications - A high-calcium limestone is required, gener-
.
ALUMINUM OXIDE
Use . Limestone in the form of lime has been used in the extraction of
-
aluminum oxide from bauxite by the Bayer process (130). The limestone was first
converted to lime which was used to make sodium hydroxide. The extraction of the
alumina is accomplished with this alkali.
This use for limestone is believed to be limited or non-existent in this
country at the present time as sodium hydroxide now is made by the electrolysis
of salt (NaCl) (J. S. Machin, personal communication, 1960).
Chemical Specifications - A high-calcium limestone containing over 97
.
percent calcium carbonate and less than 1 percent silica has been used.
ALUMINUM PRODUCTION
In the combination process of extracting aluminum from its ores, limestone
is sintered with the leach residues to form insoluble dicalcium silicate with the
silica present. Alumina and soda in the residues may then be leached out and re-
turned to the production process (18). A high-calcium limestone low in silica
would seem to be a requisite for this purpose.
AMMONIA
Sales of limestone to ammonia works are reported, but the use of the lime-
stone is not specified. It may be burned to lime and used for the recovery of
ammonia from weak ammonia liquors (Frank Reed, personal communication, 1937).
10 ILLINOIS STATE GEOLOGICAL SURVEY CIRCULAR 321
ASPHALT FILLER
Use - Limestone dust is used as filler for asphalt.
.
term limestone in specifications includes both the calcitic and dolomitic types.
Some asphalt filler probably might be classed as whiting but the color of asphalt
filler is not as critical as in the case of most whiting nor is the asphalt filler
necessarily as finely pulverized as whiting.
Goldbeck (61) states that asphalt fillers should have a fineness of 80 per-
cent minus 200-mesh. Bowles (27) also sets the fineness at approximately 80 per-
cent minus 200-mesh. The Illinois Division of Highways (79) specifies that asphalt
filler be of such fineness that 100 percent will pass a No. 30 sieve, 85 percent a
No. 100 sieve, and 65 to 100 percent a No. 200 sieve. Tentative ASTM specifica-
tions for mineral filler for sheet asphalt and bituminous concrete pavements (11)
call for 100 percent passing a No. 30 sieve, 95 to 100 percent a No. 50 sieve,
90 to 100 percent a No. 100 sieve, and 70 to 100 percent a No. 200 sieve. Amer-
ican Association of State Highway Officials (1) specifications for mineral filler for
sheet asphalt and bituminous concrete pavement require 100 percent passing a No.
30 sieve, a total of not less than 95 percent passing a No. 80 sieve, and a total
of not less than 65 percent passing a No. 200 sieve.
BARN ST ONE
Use Crushed limestone or dolomite referred to as barnstone, barn lime,
.
-
or barn snow on the floors and walls of stock barns, especially dairy
is sprinkled
barns, where it serves as a neutralizing agent and absorbent of organic wastes
and also gives a clean appearance. Presumably it may also be used as a litter
for other purposes.
General Specifications - No specifications have been noted for barnstone,
.
but stone largely passing 8-mesh or stone considerably more finely ground are both
reported to have been sold for this purpose. A white or light-colored stone of at
least reasonably high purity is probably desirable.
BRICK GLAZING
The sale of limestone for brick glazing has been reported (33) . The lime-
stone probably is ground.
BRICK MAKING
Use - A "soft plastic limestone of over 90% CaC03" with about 10 percent
.
of red clay added to it has been used in Cuba for making common brick. Bricks and
blocks also have been manufactured from limestone screenings with the addition of
weathered lava (150) Mixtures of crushed limestone and marl have been used ex-
.
perimentally for making extruded and dry pressed building brick (114).
Chemical Specifications - An impure clayey limestone or a mixture of
.
BULB GROWING
The sale of limestone for bulb growing is reported (47) . The limestone
probably should have an attractive color and be in small chips
CALCIUM CARBIDE
Use - Limestone, converted to lime, is used in the manufacture of calcium
.
carbide. The carbide is made by heating the lime with coke in an electric furnace.
Chemical Specifications - Chemical specifications (63, 64, 113, 135;
.
R. B. Ladoo, personal communication, 1959) vary but agree that the limestone
should contain 97 percent or more calcium carbonate (CaC03) The maximum phos- .
phorous (P) allowed is 0.01 percent; some specifications have lower maxima of
0.008 and 0.004 percent. Magnesia (MgO) should be less than 2 percent and some
specifications called for less than 1 percent. Silica (SiO,) maxima range between
1 and 3 percent and the maxima for iron oxide ^203) and alumina (A^O together )
vary between 0.05 and 0.75 percent. Sulfur (S) is allowable in trace amounts only.
Physical Specifications - The limestone must retain its form during burn-
.
ing and yield a tough, strong, lump or pebble lime with a minimum of fines (R. B.
Ladoo, personal communication, 1959). Some users specify oolitic limestone.
CALCIUM NITRATE
Calcium nitrate (93, 97) is made by treating limestone with nitric acid. A
high-calcium limestone is required.
CARBON DIOXIDE
Use Carbon dioxide is obtained from many sources including lime kiln
. -
gases (109) The sale of limestone for making carbon dioxide also is reported
.
(89). The stone so used probably is dolomite, and the carbon dioxide is obtained
from it by reaction with sulfuric acid (94, 128)
Specifications - No specifications have been found for stone to be used
.
for the generation of carbon dioxide, but doubtless a high-purity limestone or dolo-
mite would be desirable.
CHROMATE
Dolomite is used in making chromate (129).
COPPER PURIFICATION
The sale, or use by the producer, of limestone for the purification of cop-
per is reported (143) It is probably used as a flux or as a lime in the refining
.
DIMENSION STONE
Use - Limestone and dolomite are used as structural materials and for
.
decoration and monuments. Various terms are applied commercially to stone for
specific purposes or to stone having different size and physical characteristics,
but the names are not always exactly defined or used. The following general
categories are discussed here: building stone, including cut stone, ashlar, rough
.
building stone, rubble and veneering stone, flagging, curbing, and monumental
stone. All the grades of stone mentioned fall in the broad category of dimension
stone because size or shape limitations are inherent in different degrees in each
grade
changes and weak salt solutions, and others (5, 50, 142, 149), but no generally
accepted specific limits that distinguish between acceptable and unacceptable
building stone are known to have been set up for the tests. However, certain
maximum or minimum values may be specified by engineers or architects in con-
nection with individual projects.
Cut Stone
Use . Limestone and dolomite cut stone is used in the exterior of buildings
-
for walls, and decoration, and in the interior for walls, wainscoting,
sills, trim,
flooring, and other similar purposes. Some of it is used as monuments or carved
for decorative purposes.
Physical Specifications - Cut stone for exterior use should have good
.
polished or used with a smoothed, honed, or tooled surface. The polished stone
so employed is known commercially as marble. An attractive appearance and free-
dom from defects is desirable in all cases. Deposits from which limestone ordolo-
mite for interior use are to be obtained should generally possess the same charac-
teristics as those mentioned for exterior stone, except that weather resistance usu-
ally is not as critical.
Stone used for flooring, steps, and the like should be resistant to abrasion.
Federal specifications (149) require an abrasion hardness of 12 or more (7). Stone
that is subject to frequent washing or wetting should not contain pyrite, marcasite,
or clay partings as these materials may cause failure.
for masonry is called ashlar. Rubble is rough, unsquared, or roughly squared stone
used for masonry. Comparatively thin slabs of stone used as a facing stone are
known as veneering. Flat stones or slabs used for paving walks, patios, and
the like are called flags, flagstones, or flagging, and similar flat stones or slabs
used for making curbs are known as curbing. Rough building stone consists of
pieces of various sizes and shapes.
.
good weather resistance and essentially the same physical characteristics as cut
stone for these purposes.
Rubble and veneering stone should have good weather resistance and at
least one face with an attractive appearance. Stone containing substances such
as pyrite or marcasite, which produce stains when they weather, should be avoided
unless such stains are not undesirable. A relatively thin-bedded deposit is prob-
ably desirable for rubble production. For veneering stone, a deposit composed
largely of layers roughly 1 to 4 inches thick is commonly desirable. The surfaces
of the bedding planes in a veneering stone deposit should have pleasing appearance
and color.
Deposits used as a source of flagstone should consist principally of layers
a few inches to about six inches thick,and the bedding plane surfaces should be
relatively smooth and even. A high degree of weather resistance is a necessity,
as is good resistance to abrasion. Deposits from which curbstones are produced
also should have a high degree of weather resistance.
Monumental Stone
Use . - Limestone or dolomite is used for markers, headstones, monuments,
and the like
Physical Specifications - A uniform stone of superior weather resistance
.
ing of "Barnstone."
DYES
Use Calcium carbonate is used in the process of halogenation employed
. -
in the manufacture of dye intermediates (127).
General Chemical Specifications - Probably a high-calcium limestone is
.
should be of such size that it will "all pass through a 20-mesh screen and 97 per-
cent through 100-mesh" (117).
ELECTRICAL PRODUCTS
The sale of limestone for electrical products has been reported (89). No
details have been found regarding this use. It may be a use for limestone whiting.
the quarry in "one man" lumps but is reduced to 60-mesh at the plant.
.
EXPLOSIVES (140)
FERTILIZER FILLER
Use - Limestone and dolomite are used as fillers for fertilizers to add
.
weight, reduce caking (25), improve the physical condition of the mixture (83),
and to adjust the mixture to the desired ratios of fertilizing elements (49) . The
limestone and dolomite reduce or eliminate the physiological acidity of the ferti-
lizers and are basic constituents employed to give a "physiologically" basic prod-
uct (15, 83, 112). Dolomite and limestone are both satisfactory for filler (34).
Chemical Specifications - A reasonably pure limestone or dolomite is
.
FILL MATERIAL
FILTER STONE
Use . Crushed limestone or dolomite is used in sewage disposal plants
-
to form the beds of trickling filters over which the liquid portion of the sewage is
sprayed. The rock serves as a host for organisms which purify the sewage.
Physical Specifications - Filter stone is used in two sizes, 3^ by l\
.
inches and 3 by \\ inches (61). Careful grading is required, together with close
limitations on the amount of fines (61) Siliceous impurities are not objectable if
.
they are fine grained and evenly distributed, but pyrite, marcasite, and clay should
be avoided (27). Some types of chert are undesirable, particularly if used in the
upper part of the filter bed (101). Filter stone should have a rough surface to pro-
vide anchorage for bacteria and other organisms. It generally should withstand
20 cycles of the sodium sulfate soundness test with little or no loss of material
(4).
Remarks . - Limestone and dolomite are competitive with granite, quartzite,
trap rock, slag, and other materials as filter stone.
FLUX
Limestone and dolomite are used as fluxes in the smelting of metalliferous
ores. They combine with impurities in the ores, such as silica and alumina, to
form a fluid slag that can be separated from the metal
. .
and availability of stone may influence the kind of stone used, favoring the use
of more impure stone in certain places (34). One specification states that silica
should not exceed 2 percent and that sulfur and phosphorous should not be greater
than 0.1 percent each (62). A maximum of 0.5 percent is another figure given for
sulfur content (28). Other specifications (39) call for less than 5 percent silica,
with some plants specifying less than 3 percent, alumina less than 2 percent,
magnesia less than 4 to less than 15 percent at various plants, and phosphorous
pentoxide not more than a trace (0.005 to 0.006 percent). Still other data (60)
give a general maximum of 1 .5 percent for silica or a preference for less than 1 .0
percent (121)
Physical Specifications - Size specifications for fluxing stone vary and
.
include ranges of from 1 to 4 inches (60), 2 to 4 inches (41), and 2 inches by one-
half inch to 6 by 3 inches for high-calcium limestone and 2 inches by one-half
inch to 6 by 1^ inches for dolomite (56) .The stone should be strong, and some
users specify that it not decrepitate under the heat of the furnace (39).
Remarks - Blast furnace slag that is to be used for making cement should
.
be low in magnesia, and hence a limestone flux should be used. A figure of less
than 3 percent magnesia in such slag is given by Miller (116). For concrete ag-
gregate or railroad ballast a high-magnesia slag is harder and less subject to
slaking (41) Seven to 10 percent magnesia is said to be desirable in slag for
.
Open-Hearth Flux
Use - Limestone is used as a flux in the basic open-hearth process of
.
making steel.
Chemical Specifications - Limestone containing less than 1.5 percent
.
cause calcium oxide has a greater affinity for phosphorous than does magnesia.
Phosphorous is the most important material the flux is required to remove (20).
GLASS
Use . - Limestone or dolomite in the raw state, or burned to lime, is an
important constituent of the "batch" from which glass is made. Some glass batches
contain 20 to 30 percent of limestone or dolomite (44).
Chemical Specifications - The limestone or dolomite should have uniform
.
composition and high purity. The calcium carbonate content of the limestone prob-
ably should exceed 98 percent and the calcium and magnesium carbonate of dolo-
mite 98 percent. Iron oxide should not be more than 0.05 percent and preferably
less than 0.02 percent (39). Another specification permits a maximum of 0.3 per-
cent iron for most glass and of 0.03 percent for flint glass (60). A low sulfur and
phosphorous content is a requisite, and carbon should be kept to a minimum. Not
necessarily applicable in this country but informative are the 1959 British stand-
ard specifications for limestone for making colorless glasses (37) which require
in part that calcium oxide should not be less than 55.2 percent (98.5 percent
calcium carbonate) and total iron as ferric oxide not more than 0.035 percent.
Physical Specifications - Limestone and dolomite for glass should be
.
crushed to pass a 16- or 20-mesh sieve and should be largely coarser than 100-
or 140-mesh. The British specifications mentioned above require that limestone
for use in tank furnaces pass a three- sixteenth-inch sieve with not more than 25
percent passing a No. 120 sieve. For pot furnaces the limestone must pass a one-
eighth-inch sieve with not more than 5 percent retained on a No. 14 sieve.
LIME
Use - Lime is made from limestone or dolomite by burning them so as to
.
drive off carbon dioxide. Limestone yields a product consisting mainly of calcium
oxide whereas the product from dolomite is mainly calcium and magnesium oxides.
The great bulk of the commercial lime used in the United States consists
of calcium oxide and between and 45 percent magnesium oxide and less than 5
percent of silica, alumina, iron oxide, and other impurities. Bowles (26) describes
three kinds of lime as follows: high-calcium lime, containing not less than 90
percent calcium oxide and to 5 percent magnesium oxide; dolomitic or high-
magnesium lime, containing 25 to 45 percent magnesium oxide; and low-magnesium
lime, containing 5 to 25 percent magnesium oxide.
Of the above, the first two are by far the most widely used in the United
States; low-magnesium lime is produced in only small tonnages (Robert S. Boynton,
personal communication, 1960).
Some limes have the property of setting under water and thus are called
hydraulic limes. They are made by burning limestone containing sufficient argil-
laceous (26) or siliceous (Robert S. Boynton, personal communication, 1960) mat-
ter to form a substance that will set under water. Production in the United States
is limited but hydraulic lime is produced in quantity in Europe (Robert S. Boynton,
personal communication, 1960).
Chemical Specifications - It is likely that most high-calcium limes are
.
made from limestone containing less than 3 percent impurities, less than 5 per-
cent magnesium carbonate, more than 90 percent calcium carbonate, and often
more than 97 or 98 percent calcium carbonate. Similarly, high-magnesium limes
(excluding those made from magnesitic dolomite) probably are made from dolomites
containing less than 3 percent impurities and more than about 40 percent magnesi-
um carbonate. Low-magnesium limes would presumably be made from dolomite or
dolomitic limestone containing less than 3 percent impurities and roughly between
6 and 40 percent magnesium carbonate.
.
tical or rotary kilns. For the former between 3- (Robert S. Boynton, personal
communication, 1960) and 10-inch (29) stone may be used, but most kilns use
5- to 8-inch stone (36) In rotary kilns three-eighths to 2|-inch stone may be used,
.
although stone of narrower size limits gives better results (36) .Minus 6-mesh
limestone is used in the fluosolids process of lime burning (26) .
metal and for giving an "under surface" blue to nickel after plating (52) and to
highly polished nickel articles (ill). A fine-grained dolomite of high purity that
contains 21 percent magnesia and 30 percent lime (CaO) (134) is said to be suit-
able for making Vienna lime. The analysis of a dolomite used for making Vienna
lime (52) shows roughly 55 percent calcium carbonate (31 percent calcium oxide)
and 43 percent magnesium carbonate (21 percent magnesium oxide) with traces of
silica, iron oxide, and alumina. The grain size, porosity, and crystalline char-
acter of the dolomite also may be of importance.
LITHOGRAPHIC STONE
Very pure, uniform, fine-grained limestone or dolomitic limestone, known
as lithographic stone, having an exceptionally even texture and free from grit or
other granular impurities, was at one time extensively used for making lithographs.
The present use of the stone for making lithographs in the art field has been de-
scribed (76) It also is said to be used in the manufacture of decalcomania (100)
.
likely that a dolomite of high purity is generally desirable. The dolomite used to
treat magnesium bitterns at a California plant making perclase pebbles and light-
burned magnesia must contain less than 0.85 percent silica (Si02) and 0.16 per-
cent R2O3 (G. W.
Martin, personal communication, 1960). A dolomite used in
Pennsylvania making magnesium carbonate for insulation contained 40 to 45
for
percent magnesium carbonate and less than 1 percent silica (118) and was in 8-
to 12-inch pieces. The size of stone used in the various processes mentioned
undoubtedly varies.
MAGNESIUM CHLORIDE
A process for making magnesium chloride from Texas dolomite was devel-
oped in 1945 (156). The dolomite used contained approximately 42 percent MgC03,
55 percent CaC03, and less than 3 percent combined Si02 and R2O3.
MASONRY CEMENT
Use - Masonry cements (122) are prepared by "intergrinding portland
.
cement clinker or finished portland cement with limestone and an air entraining
plasticizer to a fineness greater than that of portland cement." Another variety
of masonry cement is made by grinding together natural cement and a small amount
of portland cement, and sometimes, in addition, a small amount of limestone.
Masonry cement also is prepared from slag-lime cement and a small quantity of
Portland cement.
No specifications have been found for the limestone ground with the other
components of masonry cements.
MEMBRANE WATERPROOFING
Use - Membrane waterproofing, placed on various highway structures,
.
consists of three layers of bitumen-treated cotton fabric (mopped with bitumen and
given a protective cover) One kind of cover consists of a mixture of petroleum
.
asphalt or coal tar pitch, coarse aggregate, fine aggregate, and mineral filler
or portland cement (77)
Physical Specifications - Coarse stone aggregate for membrane water-
.
proofing in Illinois {77) should pass five cycles of the sodium sulfate soundness
test (ASTM designation, C 88) with a weighted loss of not more than 15 percent
and should be well graded. All of the aggregate should pass a three-eighth-inch
sieve and to 1 percent a No. 200 sieve. The weighted loss of fine stone ag-
gregate for the same use should not be more than 10 percent after five cycles of
the sodium sulfate soundness test. It should all pass a No. 8 sieve and to 3
percent a No. 200 sieve.
NATURAL CEMENT
Use - Limestone
. or dolomite is calcined below the sintering temperature
to make natural cement. Either a rotary or vertical kiln may be employed.
Chemical Specifications - Limestone or dolomite, containing 13 to 35 per-
.
cent clayey material (of which silica is 10 to 22 percent) and 4 to 16 percent alu-
mina and iron oxide, is used. The remainder of the stone may be either calcium
carbonate or calcium and magnesium carbonate in any proportions (53).
Physical Specifications - The stone fed to the rotary kiln is pulverized.
.
Lump stone in pieces of about equal size (53) is charged into the vertical kiln;
the burned product subsequently is ground to a powder.
Remarks . - Natural cement is intermediate between portland cement and
hydraulic lime but differs from the latter in that lumps of it do not slake in water
(95). Natural cement was manufactured for sale at three plants in 1958. Most
of the production was used for making masonry cement (85)
PAPER
Use . manufacture of chemical wood pulp for making paper in the
- In the
tower system of the sulfite process, limestone in concrete towers is reacted with
sulfur dioxide gas in the presence of water to form calcium bisulfite, Ca(HS03)2«
This compound, together with sulfurous acid also formed in the tower, is called
"sulfite acid" and is used to digest wood chips so that a separation can be made
of the cellulose in thewood from other unwanted constituents.
Chemical Specifications - The limestone should be high-calcium limestone
.
low in magnesium, although a stone containing not more than 8 to 10 percent mag-
nesium carbonate can be used (38) Ferric oxide, alumina, and acid-insoluble
.
material together should be less than about 2 percent (38) The acid-insoluble
.
material should be light colored and settle rapidly. An analysis of a typical lime-
stone shows 53.68 percent CaO (95.77 percent CaC03) and 1.78 percent MgO
(3.72 percent MgC03), less than 0.5 percent Fe and AloOo, and less than 1
2 3
percent Si02 (123). Black specks are to be avoided, hence carbonaceous or bi-
tuminous limestones may be unsuitable. Mica flakes, graphite flakes, and pyrite
also are said to be deleterious (43)
Physical Specifications (38) - The limestone should be in coarse pieces
.
larger than 3 inches in size. Any impurities present should not occur in large
particles. In paper mills, which do not have a means of maintaining a constant
temperature of the water going through the tower, a denser limestone should be
used in summer than in winter to control the amount of calcium bisulfite in the
sulfite acid.
Remarks - In the milk-of-lime system for preparing sulfite acid, a lime
.
used in the alkaline processes of wood pulp treatment for paper manufacturing.
Some of the lime so used is made by burning the calcium carbonate cake recovered
during the processes; limestone of high purity also is added to the kiln charge to
make up for losses (123).
PHARMACEUTICALS
The sale of limestone for pharmaceuticals has been reported (131). A lime-
stone of high purity would seem to be a requisite.
PORTLAND CEMENT
Use - Limestone (including oystershell) and clay or shale are the major
.
raw materials used for making Portland cement (85) Mixtures of limestone and
.
slag or pure limestone and cement rock also are employed (85) When limestone
.
making should commonly contain more than 75 percent calcium carbonate and less
than 3 percent magnesia. Some specifications require less than 5 percent magnes-
ium carbonate (155). Phosphorous pentoxide (P2O5) should be less than 0.5 percent
and sulfur should be low.
White Portland cement requires raw materials that are very low in iron. The
iron oxide (Fe203) content of limestone for this purpose probably should be less
than about 0.01 percent. Manganese should be low.
The term "cement rock" is applied to clayey limestone, low in magnesia,
that is the major constituent of a portland cement raw mix and needs only small
additions of other clayey or calcareous material to adjust the composition of the
mix to specifications. Clay or shale are common sources of silica, alumina, and
iron oxide and "pure" limestone of calcium carbonate. Other additives may be
silica, usually as sand; alumina, as diaspore and bauxite; and iron as pyrite or
iron-bearing slag (103).
Physical Specifications - Chert nodules, other hard masses, or coarse
.
quartz grains are undesirable because they require more than normal grinding to
reduce them to a powder (155).
POULTRY GRIT
Use . - Limestone is fed to poultry as a source of calcium for the formation
of egg shells and bones. It also serves as a grit or grinding agent in the gizzard
(137).
Chemical Specifications. - A high-calcium limestone is desirable. Fluor-
ine content should not exceed 0.1 percent (L. E. Card, personal communication,
1938) because larger amounts may be harmful.
Physical Specifications - Limestone for poultry grit usually will pass a
.
4- or a 6-mesh sieve and be retained on a 10-mesh sieve. The grit may be graded
by sizes into turkey, chicken, poultry, or bird grit (27).
. .
RAILROAD BALLAST
Use
- Limestone and dolomite are used as ballast for railway tracks.
.
Raw Dolomite
Use - Raw dolomite is used for patching the hearth of open-hearth furnaces,
.
especially along the slag line (Harley C. Lee, personal communication, 1938),
for banking doors, and as a fettling material with dead-burned dolomite (108).
Chemical Specifications - Dolomite should contain more than 20 percent
.
magnesia, less than 0.05 percent sulfur, and preferably less than 2 percent silica
(108). Other specifications (41) call for the dolomite to contain more than 21 per-
cent magnesia, less than 1 percent silica, and less than 0.5 percent alumina.
Physical Specifications - The dolomite generally is screened to pass a
.
three-fourths-inch or smaller screen and the fines are removed (108). A stone that
does not disintegrate when heated is desirable.
Calcined Dolomite
Use - Calcined dolomite, sometimes called single-burned dolomite (41),
.
dolomite mentioned above probably would be suitable for making calcined dolomite
Dead-Burned Dolomite
Use - Dead-burned dolomite is made by heating to about 3000 °F a mixture
.
of dolomite and iron oxide (108). Other names sometimes applied to dead-burned
dolomite are sintered, clinkered, double-burned, and roasted dolomite (108). The
amount of iron oxide used varies from 2 to 12 percent and averages about 7 percent
(132). Dead-burned dolomite is used in large quantities for patching and mainte-
nance work in basic open-hearth furnaces, and a considerable tonnage also is
used for electric furnace bottoms (Harley C. Lee, personal communication, 1938).
It is likewise used in basic Bessemer converters, crucibles for lead blast furnaces,
and in crucibles for melting metals (72).
Chemical Specifications - Dolomite to be dead burned for use in basic
.
bottoms of open-hearth furnaces should contain less than 1 percent silica, less
than 1.5 percent combined alumina and ferric oxide, and at least 35 percent mag-
nesium carbonate (21). Other specifications (108) state that dolomite for making
dead-burned dolomite should contain "preferably 21 percent or more magnesia,
less than 1 percent of silica, and less than 0.5 percent alumina." Another maxi-
mum for silica is given as l| percent (57).
Physical Specifications - The dolomite is crushed to relatively small sizes.
.
One specification calls for pieces passing one-half inch (40). An Ohio dolomite
plant uses three sizes of washed dolomite: a minus seven-sixteenths-inch sieve
product, a minus three- sixteenths-inch sieve product, and a minus five-sixty-
fourths-inch sieve product (108).
RICE MILLING
The sale of limestone for rice milling has been reported (89)
RIPRAP
Use - Riprap consists of large blocks of stone used for foundations and for
.
filling around the base of structures subjected to erosion such as the bases of piers,
trestles, abutments, and the like. It also is placed on the banks of streams or the
the shores of lakes and other bodies of water to prevent erosion.
Physical Specifications - No generally accepted specifications for' riprap
.
have been noted; however, a weather resistant stone free from cracks, laminae, or
other structures which will cause it to split or spall is desirable. Pyrite veinlets,
clay partings, or chert generally are undesirable. The Illinois State Division of
Highways (82) requires that stone riprap "when subjected to 5 cycles of the sodium
sulfate soundness test, shall show no disintegration and not more than 10 percent
of the pieces may show splitting, crumbling or spalling." A further requirement is
that no stone be less than 6 inches in its smallest dimension (82).
ROCK DUSTING
Use . - Limestone or dolomite dust is applied to the walls, roofs, and floors
of coal mines to prevent or check coal dust explosions (70)
Specifications - The dust should be light colored (16), and to comply with
.
Use - The term "rock wool" was at one time applied largely to mineral
.
wool made from rock, but in recent years it also has been applied to mineral wool
made from slag. Only small tonnages of limestone or dolomite currently are sold
for making mineral wool. The specifications for limestone and dolomite for making
rock wool are given briefly below as a matter of reference.
Chemical Specifications - Limestones or dolomites for making rock wool,
.
often called "woolrocks, " should contain roughly between 20 and 30 percent car-
bon dioxide, which is equivalent to approximately 45 to 65 percent calcium carbon-
ate, or calcium carbonate and magnesium carbonate. The balance of the woolrock
should be principally silica, or silica and alumina. Magnesium carbonate is not
necessary in woolrocks although some operators prefer it. The same applies to
alumina. Iron sulfide is undesirable.
Physical Specifications - The size of the rock used depends in a large
.
with shale, sandstone, or other siliceous or aluminous rocks. The mixture should
meet the chemical and physical specifications given above
SILICONES
The sale of limestone for silicones has been reported (88).
STONE CHIPS
Use - Limestone and dolomite chips are used for stucco, terrazzo aggre-
.
gate, roofing "gravel, " roofing chips, as a facing material for concrete and con-
crete products, and in the making of artifical stone. Chips also are used in bi-
tuminous concrete (p. 5).
Chemical Specifications - No chemical specifications have been noted.'
.
durability, toughness, ability to take a polish, and low liquid absorption are major
requirements (19). Three sizes of terrazzo chips have been mentioned (86): those
passing a one-fourth-inch sieve and retained on a one-eighth-inch sieve; those
passing a three-eighths-inch sieve and retained on a one-fourth-inch sieve; and
those passing a one-half-inch sieve and retained on a three-eighths-inch sieve.
USES OF LIMESTONE AND DOLOMITE 25
For uses other than terrazzo, the chips should be clean and free from dust,,
soft particles, shale, and pyrite. Common sizes are thought to range between
one-eighth and one-half inch. The chips, especially those to be used for roofing,
should have good weather resistance. An attractive color is important for all uses
though it may be less important for some types of roofing chips.
STUDIO SNOW
The sale of limestone for studio snow, probably for use in motion picture
studios, is reported (47). Pulverized limestone or limestone granules probably
are used for this purpose.
SUGAR
Use (14, - Raw juice from sugar beets is agitated with milk of lime,
146) .
and carbon dioxide then passed through the juice. Impurities present are car-
is
ried down by the precipitated calcium carbonate that forms which is then removed
by thickening and filtration. The lime and carbon dioxide are made by burning
limestone at the sugar factory. In another procedure for processing sugar beet
juice, the Steffen process, pulverized lime is used to remove sugar from molasses
that results during the sugar recovery process. The insoluble calcium saccharate
so formed is recovered, washed, and returned to an earlier stage of the process
The lime so used is burned at the factory. Lime also is used to precipitate im-
purities from cane sugar Juice but is generally not made at the plant (29).
Chemical Specifications - A limestone of high purity is desired. Mini-
.
TARGET SHEETS
The sale of limestone for target sheets has been noted (88).
. . .
WATER TREATMENT
Use . - Limestone is used as a coagulent or stabilizer to prevent afterpre-
clpitation of calcium carbonate from lime-softened water (54, 69, 138)
Chemical Specifications - Limestones differing somewhat in composition
.
have been used in tests and gave apparently similar results (138). A municipal
water works is using crystalline high-calcium limestone (54) .
limestone between 150- and 325-mesh (69), finely ground limestone (54), and
limestone ground so that 90 percent will pass a 100-mesh sieve and the remainder
a 60-mesh sieve (138) are suggested sizes.
WHITING (LIMESTONE)
Limestone whiting, also referred to as whiting substitute, is made by pul-
verizing limestone, dolomite, marble, vein calcite, marl, or oyster shells (27,
87). Generally, limestone whiting should be of "good white color" (24) though in
the manufacture of some darker colored products whiting of inferior color can be
used (154). Although it is sometimes difficult to draw a sharp separation between
whiting and other calcium carbonate powders, whiting, to deserve the name, "must
be white or nearly so, and should be ground to pass 200-mesh or finer" (24)
The term "whiting" was originally applied to powders made from chalk, but
at present it includes limestone whiting as well as precipitated calcium carbonate
powders
Below is a list of uses in which or for which whiting is used. It is compil-
ed from various sources that do not always differentiate the type of whiting referred
to. It is probable, however, that limestone whiting will serve for many or most of
the purposes mentioned (23, 24, 66, 89, 96, 99, 153).
Ammonium Nitrate
Ceramic Whiting
Use . Levigated limestone whiting is used to some extent in making pot-
-
tery and porcelain ware (25). Limestone whiting also is a constituent of glazes
and enamels (24). Pulverized dolomite marble is used (120) as "a body constitu-
ent by the vitreous dinnerware producers" and in glaze batches. Experiments indi-
cate that pulverized dolomite marble has value as an auxiliary flux in suitable floor
tile compositions (120) It has been found also that in laboratory experiments ad-
.
of ceramic whiting. Both classes should contain not less than 97 percent total
carbonates, nor more than 0.25 Fe203, 2.0 percent S102, and 0.1 percent SO3
Class 1 should contain 96 percent or more CaCOo and not over 1 percent MgCO,
Class 2 may have as much as 8 percent MgC03 and as little as 89 percent CaC&3.
The whitings used in the laboratory experiments mentioned above (55) were
limestone, 80 percent through 200-mesh, CaC03, 89 percent, MgC03, 8 percent;
and dolomite, pulverized; CaO, 22 percent, MgO, 30 percent.
.
Filler in Plastics
as linoleum.
Specifications - Most of the ground limestone used for floor coverings is
.
of such size that more than 90 percent will pass a 325-mesh sieve, although coarser
grades are used in some products.
Insecticide Diluent
dolomite, or magnesian limestone. The limestone should contain not less than 98
percent calcium carbonate (dry basis); dolomite or magnesian limestone should
contain not less than 95 percent calcium carbonate and magnesium carbonate (dry
basis) (10). Other specifications (39) state that "in general calcium carbonate
content should exceed 96% but magnesian limestones containing as much as 8%
magnesium oxide are (rarely) tolerated — the MgC03 content is generally 1%.
Other maxima are: Fe 2 - 0.25%, Si0 - 2.0% and S0 - 0.1%."
3 2 3
Physical Specifications - Paint-grade limestone whiting should contain
.
not more than 1 percent of material retained on a No. 325 sieve and be largely
between 15 to 20 microns in maximum size (10). Filler should not have more than
15 percent retained on a No. 325 sieve with substantial amounts in the 10- to 44-
micron particles (10). A main controlling characteristic is the degree of whiteness
of the whiting (39) Some plants prefer a stone which breaks into rhombic particles
.
Paper Filler
Use .Calcium carbonate fillers are widely used in magazine and bible
-
papers (151). Both limestone whiting and by-product precipitated calcium carbon-
ate are used as paper fillers (133). Cigarette papers contain a special precipitated
calcium carbonate (151).
Specifications - No chemical or size specifications for limestone whiting
.
were noted. Stone used for making paper filler probably should be white, have
high purity, and be ground to a fine powder. Willets (151) states that limestone
whiting for paper is separated by various air-floating and wet techniques.
Putty
The essential ingredients of putty are whiting and linseed oil (154). Lime-
stone whiting is much used for this purpose in the United States. Among other
USES OF LIMESTONE AND DOLOMITE 29
desirable properties are low oil absorption and a light gray or cream color (154).
The ASTM specifies that putty-powder grade whiting should not have more than 30
percent retained on a No. 325 sieve (10). Fineness of grain size and freedom
from grit are desirable.
Rubber Filler
Use - Pulverized limestone is used as a filler in rubber of various sorts.
.
from the poorest to the best grades of whiting for rubber filler:
General Physical Specifications - Stone for these uses should have good
.

USES OF LIMESTONE AND DOLOMITE 39
INDEX
ADDENDA
AGRICULTURAL LIMESTONE
Agricultural limestone is said (166) to act as a control to the quantity
of strontium 90 removed by plants from soil contaminated by atomic fallout.
(See also page 8.)
BURNISHING PEBBLES
Rounded limestone pebbles are used in mills in which castings are
burnished. No specifications for the limestone are known. Some pebbles are
about one-half or three-fourths inches in diameter. The amount and nature of
the impurities in the limestone may well affect their suitability. Presumably
dolomite pebbles might be similarly used.
DEAD-BURNED DOLOMITE
Dolomite to be dead-burned (167) usually is of high purity, containing
less than 1 percent silica and 0.5 percent alumina. It is used in two sizes,
minus three-eighths inch + 6 mesh and -6 mesh + 20 mesh. (See also page 23.)
bisulfite produced is suitable for use in the bisulfite paper-pulping process (157).
Presumably high-purity dolomite would be used. (See also pages 18, 19.)
PAPER
According to Mills (170), the requirements of most paper companies in
the state of Washington would be met by a limestone containing not less than
95 percent CaCO_, less than 3.0 percent MgO, less than 1.5 percent silica, and
less than 0.5 percent R 0_.
9
Specifications for high calcium limestone and for dolomite to be used in
the Jensen Tower System of sulfite pulp production are as follows (163):
High calcium limestone —
CaO more than 53 percent; MgO less than
1.5 percent; Si0
9
Fe„0„, and Al 0_ together less than 1.5 percent; and organic
,
PIGMENT
Pulverized limestone is used as a pigment in paint, plastics, putties,
and wood fillers (161). This is presumably a use for limestone whiting. (See also
pages 26-29.)
REFRACTORY DOLOMITE
The A.S.T.M. (160) classification for raw refractory dolomite on an
"as received" basis requires a minimum of 16 percent magnesium oxide and gives
USES OF LIMESTONE AND DOLOMITE 43
the following maxima for impurities: silica 1.75 percent; aluminum oxide plus
titanium oxide 1.50 percent; and sulfur 0.08 percent. (See also pages 22-23.)
ROCK DUSTING
According to recent Polish research, the material in rock dust finer than
10 microns is not effective in arresting explosion propagation,and rock dust con-
taining more than 10 percent minus 10 micron material is ineffective (165) .
. SWEEPING COMPOUNDS
The sale of ground limestone to janitor supply houses for use in sweeping
compounds has been reported (K. K. Landes, personal communication, 1961).
