Foamed Concrete - an overview | ScienceDirect Topics
Foamed concrete is a blend of cement, sand, water, and prefoamed foam with the vast majority of foamed concrete containing no large aggregates but only fine sand (Fig. 1.8) [4].The extremely lightweight foamed concrete contains only cement, water, and foam. The raw materials used for the production of foam concrete are binding agent, aggregates, foaming agent, and water.
