Application Details

Light weight cellular concrete is a material that solves many heavy-duty construction problems. Used beneath roadways, bridges, and ramps, buildings and other structures, it reduces soil loading while adding compressive and shear strength.

Composed of cement, water and small, stable air cells, cellular concrete offers a unique range of benefits. Cellular concrete can be produced quickly and easily on site by mixing a preformed foam into a Portland cement slurry. This material is mixed with cement and water in a conventional rotary mixer to distribute the air voids uniformly and form a highly stable cellular structure. Because production of preformed foam involves no gas-releasing chemical reactions, the foam doesn’t expand once it enters the cement and the density remains constant. The cement paste attains initial set in about 90 minutes. Although the foam in the concrete matrix is stabilized after the initial set, six to ten hours must pass before a placement of cellular concrete can be topped by a subsequent lift.
