A Study on Partial Replacement of Natural Granite Aggregate with Pelletized Fly Ash Aggregate

In this paper the use of pelletized fly ash aggregate in concrete as a partial replacement of granite aggregate has been examined. The concrete so produced is light weight in nature and the development of such concrete with cold bonded pelletized fly ash aggregate is to minimize the conventional aggregate, which results in protection of the natural environment. With the partial replacement (0%, 25%, 50%, 75% and 100%) of natural granite aggregate by pelletized fly ash aggregate, the strength properties of concrete such as compressive strength, split tensile strength, flexural strength and young’s modulus of elasticity are studied.
