Properties and applications of foamed concrete; a review

•Stability of fresh foamed concrete is controlled by type and volume of foam agent added.•The compressive strength is a primary function of the desirable density design.•Foamed concrete has potential characteristics to produce structural applications.•Foamed concrete is superior fire resistance compared to normal concrete.

Foamed concrete possesses characteristics such as high strength-to-weight ratio and low density. Using foamed concrete reduces dead loads on the structure and foundation, contributes to energy conservation, and lowers the labor cost during construction. It also reduces the cost of production and transportation of building components compared to normal concrete and has the potential of being used as a structural material. This paper provides a review of foamed concrete constituents, fabrication techniques, and properties of foamed concrete. This literature review also aims to provide a comprehensive insight into possible applications of foamed concrete in the construction industry today.
