Hardened Properties of Foam Concrete

The physical properties of the foam concrete are related to the dry density. The variation is seen in the tabulation given in the table below. Typical Properties of Foamed Concrete in its Hardened State: 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. The foamed concrete does not possess an equivalent strength similar to an autoclaved block with similar density. Under the action of load, internal hydraulic pressure is created within the structure, which causes 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 foamed concrete density here ranges from 400 to 1400kg/m3. Advantages of Foam Concrete: The foam concrete mix does not settle. Hence it does not need any compaction; the dead weight is reduced as it is lightweight concrete, and The foamed concrete under its fresh state has a free-flowing consistency. This property will help in filling the voids. The foam concrete structure has excellent load spreading and distributing capability; the concrete foam batches are easy to produce, so quality checks and control are easily done.
