Abstract: Aerated concrete is a type of light weight concrete which consist of a binder, fine aggregate and an aerating agent. Aluminium powder is the most commonly used aerating agent and it reacts with calcium hydroxide liberating hydrogen bubbles which causes the air entrainment of the mix. In this paper, study of properties aerated concrete incorporating additives like fly ash as a replacement to cement, which lead to the consumption of waste products. A cement to fine aggregate ratio of 1:2 have been adopted and water cement ratio is fixed as 0.45 by trial and error method.
