Properties of Zeolite as an Air-Entraining Agent in Cellular Concrete

Abstract

This paper describes a new type of lightweight concrete using zeolite as an air-entraining agent. The cement paste expands in the presence of the zeolite powder, and after setting and hardening a cellular concrete is formed. The compressive strength of concrete after standard curing for 28 days is 4.5 to 5.5 MPa, and the density is about 750 to 850 kg/m3. The zeolite in concrete can also react with the cement paste during its hydration, and therefore the strength of concrete can increase further with age.
