LMU/Mwh
P-Plant
Total power expenses for cement in bin manufacturing divided by the corresponding quantity of MWh
consumed during a given period.
For plants with several main substations with distinct contracts, this definition applies separately to each
main substation for the shops serviced (Example: Quarry with a dedicated substation). For plants
generating their own power, resources used to produce this power should only appear once: - Either in the
cost of MWh, but only if the resources used are completely known. In this case not only expenses but also
related resources (hours, population, MJ, etc...) will be charged to MWh and not to clinker or cement. - Or in
Fuel, labor, etc...for the production or clinker or cement. In such a case, the expense for this production of
MWh is nil.
= Power expenses/Power consumed In both cases, the average cost of MWh used is calculated as :
(Expense of MWh production+Purchase of MWh-Sale of MWh) / MWh used (CE008X divided by CR056X)
multiplied by 1000

The average specific heat cost or cost of fuel mix is the average heat expense of the different fuels used for
clinker production, weighted by the % of heat consumed.
For plants generating their own power, fuels already included in the power cost can not be taken into
account. The costs of the in-house power plant should only appear once in the clinker production cost: either
as fuel and fuel costs, or in the power cost.
From 2006, this indicator will be also used for the calculation of the Alternative Fuels gross savings (see
PR086X).

Alternative raw materials expenses / t alternative raw materials used in the raw mix
ARM cost
Delivered cost of one tonne of alternative raw materials (non natural) used as a raw mix component. It can be
negative if its use generates a revenue.
Alternative raw materials (ARM) are wastes or by-products of other industries used by the cement plant as a raw
material component. The objective typically is to provide one or more major chemical components (CaO, SiO2,
Al2O3, Fe2O3) to the raw mix and thus substituting, partly or totally, quarried raw materials. ARM may
sometimes be used to provide a process improvement (e.g. energy contribution, burnability, emission reduction,
quality improvement), by modifying a characteristic of the raw mix such as the chemical composition of its minor
elements (e.g. fluorine, sulphur, alkali).
The cost can be positive (i.e. purchased) or negative (i.e. gate fee received), generating a revenue.
The ARM is chemical transformed to become part of the clinker matrix. It may be introduced at any point in the
raw mix preparation circuit or kiln.
Alternative material added to the raw mix preparation or pyro-process (kiln) line, prior to the discharge of the
rotary kiln, is classified as an ARM. Any alternative material (e.g. slag, fly-ash, etc) introduced after the clinker
cooler discharge is considered a cementitious additive. By exception, granted by the TC, any alternative material
added to the clinker cooler can be classified as an ARM, if the material is transformed into clinker (integrated into
the matrix).
If an ARM has significant carbon content (fuel value), the quantity consumed and its cost are still reported as
ARM, under the appropriate category. In addition, its energy contribution to the kiln system is reported as
alternative fuel, under the category Energetic ARM (CR120X ).
All materials classified as ARM, according to the above definition, are considered in the calculation of the raw
mix/clinker ratio.
This indicator is calculated as a weighted average of the ARM tonnages and ARM cost/ton:
AR617X = (AR656X i * CR209X i + AR656X i+1 * CR209X i+1)/(CR209X i + CR209X i+1 ) i, i+1, ...
= categories of ARM (see indicator CR210X )
i, i+1, ... = categories of ARM (see indicator CR210X )
AR656X - Cost of ARM, site delivered, per ton of material
CR209X - Quantity of ARM

In order to enable the calcul of the alternative fuels (AF) gross savings (PR086X), each plant must define a
reference fuel cost (in "as received" basis). This reference fuel cost is defined as the fuel mix cost if no AF had
been used: it is the weighted average of the fossil fuels cost and the respective percentage that is replaced by
AF.
Its definition will enable the calculation of the alternative fuels gross savings (indicator PR086X) according to the
methodology (Cost ref fuel (AR749X) - cost fuel mix (AR607X))* Tons KK (PA021X)* CC (CR008X)). The plant
has the responsibility to calculate the reference fuel cost and to report it correctly. It is recommended that its
calculation be consistent from one year to another; it should be the closest reflexion of the actual situation.
Find below some examples that can help you to understand how to calculate this cost.
Plant A
Fuel mix: 30% coke; 25% coal; 1% used oil; 5% solvents; 19% tyres; 15% MBM; 5% biomass
Case 1: assuming that used oils replace fuel oil and that the other AF used replace both petcoke and coal.
The reference fuel cost will be a weighted average of the respective of fuel oil, coal and coke and its percentage if
no AF had been used.
Ref fuel cost 1 = 49,5% coal * cost coal + 49,5% coke * cost coke + 1% fuel oil * cost fuel oil
Case 2: assuming that used oils replace fuel oil and that the other AF replace coal. The reference fuel cost will be
a weighted
average of the respective costs of fuel oil, coke and coal and its percentage if no AF had been used.
Ref fuel cost 2 = 1% fuel oil* cost fuel oil + 30% coke * cost coke + 69% coal * cost coal
Case 3: assuming that AF replace only petcoke. The reference fuel cost will be a weighted average of the
respective costs
of coal and petcoke and its percentage if no AF had been used.
Ref fuel cost 3 = 25% coal * cost coal + 75% petcoke * cost petcoke

Otherwise, this category regroups the alternative raw materials (ARM) whose calorific value contributes to the
plant's alternative fuels substitution. Consequently, its heat value should be included in the specific heat
consumption of the kiln (indicator CR005X).
Alternative fuels included in this category must contribute significantly to the raw mix through their ash content
(e.g. sludge with 75% water content do not enter in this category).
The quantity and the gate fees should be reported in the ARM reporting.
The objective is to report only the impact of this category on the energy used by the kiln. Therefore, only the
calorific value (%) will be reported. The quantity and the gate fees will be reported in the ARM reporting to avoid
double counting. The cost of the energy brought by this ARM will be considered automatically as 0 in the AF

Categories of Alternative Raw Materials
ARM category
This indicator is a description of the alternative raw materials (ARM) categories defined by the Resource
Recovery Department (DPC) and validated by the BRS Validation Committee.
To fulfill the ANNUAL report, the cement plants must classify each ARM used at the plant under one of the
defined categories. It is mandatory to associate to each ARM category used at the plant, the quantity consumed
(CR209X) and the cost/ton (AR656X) The addition of the quantities of each ARM category consumed equals the
indicator CR160X.
The official ARM categories are:
Alumina sludge: Alumina rich sludges (Water > 30%; Al2O3 > 30% dry basis), including sludges of alumina
hydroxide, stainless steel, ceramic, iron hydroxide, incinerator. Red & brown mud have a dedicated category.
Sludge Other: All other sludges (Water > 30%), including sludges of silanes, iron hydroxide, CaF (calcium
fluoride), ceramic, water treatment. Whenever possible, filter cake material approaching 30% water should be
classified in the most appropriate category below. Waste clay should be classified in "Alumina other".
Power plant ash: Includes bottom ash, flyash (wet or dry) from coal fired power generating facilities. It does not
include cementitious additives. It may include tonnages reported under CR107X and CR139X indicators.
Ash other: Includes paper ash, incinerator ash, pulp and paper ash. It does not include pyrite ash, classified under
pyrite cinders category. It does not include cementitious additives. It may include tonnages reported under
CR107X and CR139X indicators.
Slag - all types: All slags resulting from metal (ferrous, non-ferrous) refining. Includes iron, steel, convertor, blast
furnace, granulated, pelletized, ground, zinc, copper materials. It does not include cementitious additives. It does

P-Plant
Percentage (in as received basis) of non natural material, or of material derivating from a treatment which goal is
to extract or process another product, used as a raw mix component.
Raw materials (ARM) are wastes or by-products of other industries used by the cement plant as a raw material
component. The objective typically is to provide one or more major chemical components (CaO, SiO2, Al2O3,
Fe2O3) to the raw mix and thus substituting, partly or totally, quarried raw materials. ARM may sometimes be
used to provide a process improvement (e.g. energy contribution, burnability, emission reduction, quality
improvement), by modifying a characteristic of the raw mix such as the chemical composition of its minor
elements (e.g. fluorine, sulphur, alkali).
The cost can be positive (i.e. purchased) or negative (i.e. gate fee received), generating a revenue.
44/95
The ARM is chemical transformed to become part of the clinker matrix. It may be introduced at any point in the
raw mix preparation circuit or kiln.
Alternative material added to the raw mix preparation or pyro-process (kiln) line, prior to the discharge of the
rotary kiln, is classified as an ARM. Any alternative material (e.g. slag, fly-ash, etc) introduced after the clinker
cooler discharge is considered a cementitious additive. By exception, granted by the TC, any alternative material
added to the clinker cooler can be classified as an ARM, if the material is transformed into clinker (integrated into
the matrix).
If an ARM has significant carbon content (fuel value), the quantity consumed and its cost are still reported as
ARM, under the appropriate category. In addition, its energy contribution to the kiln system is reported as
alternative fuel, under the category Energetic ARM (CR120X ).
All materials classified as ARM, according to the above definition, are considered in the calculation of the raw
mix/clinker ratio.

This is a general indicator to show the overall implementation status of best practices in the plant.
Each of the Industrial Pillar questionnaires except Capital Efficiency contains the question "Best Practice
Implementation". This measures the implementation of the best practices specifically related to that lever,
e.g. implementation of best practices related to Product & Quality management. The Best Practice
Compliance Status is an average of the scores for the Best Practice Implementation question in each of the
Industrial Pillar questionnaires (Energy, Maintenance, Product & Quality and Production & Process).
Calculate an average of scores from the four questionnaires. Convert from letters to number and calculate an
average as shown in the example below. Convert the result back to a letter: Less than 1.5 is E Between
1.5 and 2.5 is D Between 2.5 and 3.5 is C Between 3.5 and 4.5 is B Above 4.5 is A and 4.5 is B Above 4.5 is A

Free Lime
3-Burning
s'(Free Lime) divided by (0,2 * Mean (Free Lime) +0,1) during a given period.
The free lime uniformity index is the main indicator to characterise the stability of the burning conditions.
We assume, that under very stable burning conditions the SD of the free lime is not more than 20% of the
absolute value (Coefficient of Variation < 20 %) - in this case a kiln is class A. The term "+0.1" in the
calculation stands for the accuracy of the free lime analysis. Otherwise we would calculate completely
meaningless values for very low absolute free lime figures. Of course this figure is more meaningfull, if the
free-lime is a good measure of the burning conditions (what is not the case for some of our kilns - mainly
some of our long kilns). Therefore, this indicator has to be seen in connection with the absolute amount of
the free lime.

The alternative fuels gross saving is the economy made by a cement plant with the replacement of fossil fuels by
alternative fuels.
Alternative fuels are non fossil fuels which replace the fossil fuels (coal, petcoke, oil, HVF, gas) in the cement
production process. The Alternative Fuels glossary is included in the Excel file attached below.
The gross savings are calculated taking into account the difference between the cost of the reference fuel
(AR749X) and the cost of the fuel mix (AR607X), multiplied by the total heat consumption (CR008X) and the
clinker production ( PA021X).
Cost reference fuel = 1,95 LMU/GJ
Cost fuel mix = 1,10 LMU/GJ
Heat consumption = 3962 MJ/t KK
Clinker production = 737 000 t

The IQP measures the percentage of time results for up to 5 quality parameters selected for each product
produced by the plant, are at or within set upper and/or lower limit(s).
The IQP (Indicateur Qualit Produit or Product Quality Indicator) is an indicator of product quality, as agreed
between marketing & sales and manufacturing staff, based on customer requirements for all product(s) produced
at a plant.
The indicator measures the percentage of time results for up to 5 quality parameters selected for each product
produced by the plant, are at or within set upper and/ or lower limit(s).
Parameters selected should reflect the performance characteristics desired by the main customers using each
product e.g. cement physical, chemical or paste, mortar, micro-concrete or concrete test results. The upper and/or
lower limit(s) for all parameters of each product are jointly set by manufacturing & marketing personnel based on
market requirements and plant capabilities. The limit(s) are set, such that an IQP of 100 should result in zero
customer complaints attributed to cement quality.
For reporting purposes, the IQP will be a single number calculated for each plant based on results obtained
during a calendar year.
A plant can be a cement plant, or a grinding facility (cement or slag)

The LAI measures the accuracy of chemical and physical tests performed in the plant's laboratories,
The LAI is based on the results of the Lafarge interlab test (IU) that is performed on a yearly basis. The
participation to the interlab is mandatory. The indicator is calculated for each plant by the Technical
Centres. The results are communicated plant by plant, before the end of each year. The plants are then
responsible for feeding the indicator into the CKHC data base.
In the preparation phase, a common cement type (pure OPC) is agreed upon by TC's as the basis for the IU.
LCR is in charge of the preparation. The first step of the process is to define, at the level of the TC's, which
physical and chemical parameter should be measured by each plant, depending on the local standards and
specific requirements. Between 18 and 24 parameters are chosen. The second step is to perform the
measurements at plant level, on the IU sample which has been sent by LCR. The third step is to feed the results
into the LAI database, for which an access right is needed. Results have previously to be validated by each lab
manager. The fourth step is the statistical analysis of the results (TC's+LCR+DPC). It allows to calculate the
target value for each parameter In the last step, the tolerance range is applied to each measured value.
The number of parameters that fall at a distance to the target lower than the tolerance is divided by the total
number of parameters measured, which gives the LAI (0-100%). This indicator is consolidated at BU level by
taking cement production into account. The indicator is to be taken into account when elaborating the PIP's. The
following performance classes have been defined : 100 % > LAI > 85 % => A 85 % > LAI > 75 % => B 75 % >
LAI > 65 % => C 65 % > LAI > 55% => D 55 % > LAI => E The target for all plants is a sustainable A class.

have been evaluated on the basis of a representative core drilling and geochemical analysis (exploration
and exlpoitation drilling)
technical and economic operability has been recognised
immediate availability is known
Purchased Natural and Secondary Raw Materialscan be taken in consideration for the time where a contract with
the supplier exists
The Reserves of readily available components have not to be proven a component is "readily available" if it is
ensured that the material or a adequate replacement can be purchased on long term basis without increasing the
cost for more than 5%
For limestone do not forget to substract the amount of limestone used for other purposes (used in cement
production, ...) when calculating the long term plan
The responsible Technical Centre prepares block models for all natural reserves and based on this
information a long term mining plan which takes into consideration all raw mix components (also purchased
natural and secondary materials). Based on this long term mining plan the indicator is calculated as
following:
For each component:
(PR [ t ]) / (KRC * fCl * % of use in mix )
89/95
Where:
PR = Proven Reserves of this component
KRC = Clinker Capacity (PR046X)
fCl = Factor Raw mix / Clinker (result of the long term plan)
