It is a light weight concrete produced by introducing large voids in the concrete or mortar. Its density varies from 3 kN/m3 to 8 kN/m3 whereas plain concrete density is 24 kN/m3. It is also known as aerated,foamed or gas concrete.Properties of cellular concrete: It has the following properties:

1. It has low weight.                                       

2. It has good fire resistance.

3. It has good thermal insulation property.

4. Thermal expansion is negligible.

5. Freezing and thawing problems are absent.

6. Sound absorption is good.

7. It has less tendency to spall.

Uses of Cellular Concrete

1. It is used for the construction of partition walls.

2. It is used for partitions for heat insulation purposes.

3. It is used for the construction of hollow filled floors.
