INTRODUCTION
Foam concrete is a type of porous concrete.
According to its features and uses it is similar to
aerated concrete.
The synonyms are:
1) Aerated concrete
2) Lightweight concrete
3) Porous concrete
INTRODUCTION
Light weight concrete - or foamed concrete - is a
versatile material which consists primarily of a cement
based mortar mixed with at least 20% of volume air.
It possesses high flow ability, low self-weight, minimal
consumption of aggregate, controlled low strength and
excellent thermal insulation properties
It can have a range of dry densities, typically from 400
kg/m3 to 1600 kg/m3 and a range of compressive
strengths, 1 MPa to 15 Mpa
For Normal 3000 PSI Concrete the strength is 21 Mpa.
Foamed Concrete can be placed easily, by pumping if
necessary, and does not require compaction, vibrating
or levelling.
It has excellent resistance to water and frost, and
provides a high level of both sound and thermal
insulation.
Constituents materials
1. Constituents of base mix
2. Foam.
1) Fire resistance :-
Foam concrete is extremely fire resistant and well suited
to applications where fire is a risk.
Test have shown that in addition to prolonged fire
protection, the application of intense heat, such as a
high energy flame held close to the surface, does not
cause the concrete to spall or explode as is the case with
normal dense weight concrete.
Foamed Concrete
2) Thermal insulation :-
Foam concrete has excellent thermal insulating properties
due to its cellular microstructure.
The thermal conductivity of foam concrete of density
1000 kg/m3 is reported to be one-sixth the value of typical
cement–sand mortar .
