Investigation on the Development of Light Weight Concrete with Sintered Fly Ash Aggregate and Activated Fly Ash in Blended Cement

Abstract

The use of activated fly ash in blended cement and sintered fly ash aggregate in concrete as a partial replacement of granite aggregate has been examined .The concrete so formed is light in nature(upto 40% reduction in unit weight)and development of such concrete minimises consumption of granite rock resulting in the protection of natural environment. Present investigation considers M20 and M25 grade concrete It is observed that with partial (20%,30% and 40% by volume)replacement of natural granite aggregate by sintered aggregate the physical properties of concrete such as compressive strength and Young's modulus of elasticity are retained.
