Cellular Concrete

Definition: a low-density product consisting of portland cement, cement-silica, cement-pozzolan, lime-pozzolan, or lime-silica pastes, or pastes containing blends of these ingredients and having a homogeneous void or cell structure, attained with gas-forming chemicals or foaming agents.- ACI Concrete Terminology

Cellular concrete is a mixture of cement, water, and preformed foam. The purpose of the foam is to supply a mechanism by which a relatively high proportion of stable air voids can be induced into the mixture and produce a cellular or porous solid upon curing of the mixture. When cellular concrete hardens, it has an oven-dry density of 50 lb/ft3 (.8 t/m3)or less.
