Foamed Concrete can be defined as a type of Cellular Lightweight Concrete (CLC); it doesn’t contain any Coarse Aggregate (Gravel). The whole slurry contains only the Cement, Sand, Fly ash in different proportions and Foaming agent. The foam used in the mortar can be of two types; Natural and Synthetic. The natural foam liquid can be prepared by using the Soap nuts (from small trees in the Lychee family, native to warm temperature to tropical regions of the world). The synthetic based foam agents are easier to handle and are cheap. They can be stored for a longer period. Lesser energy is required to produce these foams. The protein based foam is costly but have high strength and performance. The foam can be generated by the foam liquid using the foam generator. The slurry and the foam mixture can produce a variety of foamed concrete densities ranging from 400 to 1800 Kg/m3.This CLC block may be used in non-structural parts of buildings like partition walls or light load bearing walls. Cellular lightweight concrete are made in different proportions based on the materials in same densities with natural foaming agent then their compressive strengths and density is tested and compared with normal weight concrete.
