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 Geofill cellular concrete the same as lightweight concrete?

  • No. Geofill 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, Geofill cellular concrete uses the internal air cell structure instead of an aggregate and exhibits densities from 20 to 90 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 Geofill cellular concrete cost?
