Aerated Lightweight Concrete (ALWC) is an ultra-light weight concrete masonry product. It’s weight is 1/5 times less than ordinary concrete due to distinct cellular structure having millions of air voids trapped in concrete.. This cellular structure in concrete gives LWC a large variation in physical characteristics exceptionally. LWC contains sand, cement, lime, fly ash, gypsum, aluminium powder paste(AAC), water and an expansion agent(Foaming agent). Silica sand which is main the raw material used in the maximum volume in LWC, is one raw material in world's most abundant natural resources list. The final concrete is approximately up to five times of the volume compared to the raw materials volume used, it depends on the requirement of strength and density. Due to this large increase in volume, ALWC is very resource efficient for construction. In construction sector concrete is highly consumed and the raw materials for the concrete used in building construction are in chronic shortage and the responsible for associated environmental damage. From the last decade, construction industry has started conducting various researches all over the world on the utilization of easily available raw materials in building construction. This work is done to investigate the property changes in lightweight concrete against the ratio of the air entrapped in concrete. There are two main objectives of the project are to produce aerated lightweight concrete in laboratory and to determine the effectiveness of voids using foam in mortar. To determine and compare strength of aerated lightweight concrete, at different ratio of the air entrainment in the concrete.
