Abstract

Cellular concrete (CC) is a foamed mixture of cementitious materials, fine sand, and water, which once hardened results in a consistent, lightweight concrete containing millions of evenly distributed, uniformly sized macroscopic air-voids of approximately 0.1 to 1 mm size. In the present study, cellular concretes with varying proportions of portland cement, fly ash, and lime were explored in a comprehensive laboratory test program related to porosity, compressive strength and resistance to Freeze-Thaw (F-T) including dynamic modulus of elasticity. Test results show that compressive strength of cellular concrete is primarily as a function of the porosity and w/cm regardless of type of cementitious material and curing age. On the other hand, the CC mixture with high porosity does not necessarily result in higher resistance of F-T, but the CC concrete generally has good F-T resistance compare to non-aerated concrete.
