Experimental Analysis of Demolished Concrete by Using its Coarse Aggregate as Recycling Material

Concrete is most widely used in construction material all over the world in view of its compressive strength, Moulding ability, structural ability and economic consideration. Recycling of Demolished concrete aggregate means the process of collection and reusing it in their original form. Use recycled aggregate (RCA) in concrete is helpful for protection of environment and economic point of view. Recycled aggregate are the material for future, as it is used up to 20 % of replacement by natural aggregate available from quarries. This paper gives application of coarse aggregate from recycled demolished concrete when used in M20 mix proportion with different percentage of recycled aggregate replaced with natural one and its result analysed at 7,14, and 28 days of compressive strength.
