What is 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.”

Is cellular concrete the same as lightweight concrete?

No. Cellular concrete weighs considerably less than typical “lightweight” concrete. By definition “lightweight” concrete is a concrete made with aggregates that are lighter than typical stone aggregates. Typically, lightweight concrete has a density + 120 lb. / cu.ft. In contrast, cellular concrete uses the internal air cell structure instead of an aggregate and exhibits densities from 20 to 60 lb. / cu. ft.

The American Concrete Institute International ( ACI -116R-90) offers this definition:
“Concrete, lightweight – concrete of substantially lower density than that made using aggregates of normal density.”

Is there shrinkage?

Actually, the shrinkage is minimal at less than 0.6%. Furthermore, any cracking of the material does not affect the load bearing capacity. (Similar to soils)

How much does cellular concrete cost?

Cost-effective cellular concrete varies in price by geographical area and by application requirements. Your MixOnSite, LLC representative will be glad to assist you with budget numbers and binding quotations for our products and services.
