Foam concrete is a type of aerated lightweight concrete foam concrete does not contain coarse aggregate and can be regarded as an aerated mortar. Foam concrete is produced when pre-formed foam is added to slurry the function of foam is to create an air voids in cement–based slurry. Lightweight aggregate foamed geopolymer concrete (LWAFGC) was measured at room temperature according to the ASTM D using the transient heat method using the KD2 Pro.

This results in a cellular lightweight concrete. High carbon ash recycled aluminum waste and zeolite powders are additional mechanical structures suitable in the production of cellular lightweight concrete. These cells may account for up to 80 of the total volumne. lightweight concrete sample made is with a variety of different slump values while the portland cement composite (PCC) sand pumice and rice husk ash (RHA) materials are kept constant. There are two main parameters that determine the mechanical properties of lightweight concrete each of which is the sample density and water cement ratio.
