Conventional building materials are widely used in a developing country. These types of material are quite costly. The Non Auto claved Aerated Concrete(NAAC) is versatile lightweight concrete and they are generally used as blocks. The study of Auto claved Aerated Concrete replacing natural sand with fly ash is investigated. This paper aims to investigate strength characteristics of light weight concrete block produced using the gradation of Crumb rubber, on conventional fine aggregate with the trial mix proportions by the weight of ordinary Portland cement, fly ash, crumb rubber as a substitution for river sand. The use of waste rubber tire leads to the protection of environment and also it helps to preserve the natural fine aggregates. The various trial mixes were tried and the compressive strength, water absorption and density of cellular concretes were determined at the age of 14days.
