The main objective of this paper is to comparing the different types of light weight concrete according to their physical properties. Light weight concrete are widely used in all over the world, these types of concrete having densities ranges 450-1800 kg/m3 and are more sustainable than burnt brick clay or ordinary types of concrete. In this paper a deep discussion are carried out between the properties of AAC, CLC and fly ash. AAC(Autoclaved aerated concrete ) is a light weight concrete material that was developed in many years ago, the main constituents used in making of this type of concrete is cement grade53 , gypsum, class C lime (hydrated lime), aluminum powder(.05-.25% by wt of cement) , fine aggregate or fly ash (class F) combining with definite proportions. CLC (Cellular light weight concrete) is another light weight concrete material which are widely used in making infrastructure and high rise building, the main ingredients of making CLC is cement(OPC grade 53), Fly ash (class F),sand (passing 2mm sieve) , foaming agent(either protein based or synthetic based). Fly ash is also taken in this paper as a light weight concrete because it replaces partially fine aggregate and fully coarse aggregate the raw materials of this type of concrete is cement (grade53/grade43), Fly ash (class F),sand (passing 2mm sieve). On keeping density as a constant parameter their load carrying capacity in compression, thermal insulation and water absorption are to be tabulated and then conclusions are made by their best performance.

Keywords- Cellular lightweight concrete, autoclaved aerated concrete, fly ash concrete, comparative study, compressive strength
