Foam concrete can be defined as a cementitious material that consists of minimum 20 percent of foam, that is mechanically entrained into the plastic mortar. The dry density of foamed concrete may vary from 300 to 1600 kg/m3. The compressive strength of foam concrete determined at 28 days, ranges from 0.2 to 10N/mm2 or can go higher. unicorn chemical is leading construction chemicals comapny who also provice concrete foam in lahore islamabad pakistan

Foam concrete is differentiated from air entrained concrete in terms of the volume of air that is entrained. The air entrained concrete takes in the air of 3 to 8 percent. It also differs from the retarded mortar and aerated concrete for the same reason of percentage of air entrained.

The thermal conductivity of foam concrete ranges from 0.1W/mk to 0.7W/mk. The drying shrinkage ranges from 0.3 to 0.07% at 400 and 1600kg/m3 respectively. unicorn chemical is leading construction chemicals comapny who also provice concrete foam in lahore islamabad pakistan

The foamed concrete does not possess an equivalent strength similar to an autoclaved block with similar density. Under the action of load, there is internal hydraulic pressure created within the structure, which would cause the deformation of the foam concrete.

The hardened foam concrete has good resistance against freezing and thawing. It was observed that the application of foamed concrete in an area of temperature ranging from -18 degree Celsius to +25 degree Celsius showed no signs of damage. The density of foamed concrete employed here range from 400to 1400kg/m3. unicorn chemical is leading construction chemicals comapny who also provice concrete foam in lahore islamabad pakistan
