FAQs - Cellular Concrete Composition

What is the composition of cellular concrete?
Cellular concrete is generally defined as a "lightweight cementitious material that contains stable air or gas cells uniformly distributed throughout the mixture at a volume greater than 20%." Cellular concrete can be thought of as a concrete, which utilizes a stable air cell structure rather than traditional aggregate. The American Concrete Institute International (ACI-116R-90) offers this definition: "Concrete, cellular: a lightweight product consisting of portland cement, cement-silica, cement-pozzolan, lime pozzolan, 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."
