Large quantities of construction and demolition wastes are continuing being generated which are just being dumped in the landfills. This requires large areas of land which is becoming difficult to find. The best solution would be to recycle and reuse the demolished waste which would not only help in predicting the environment but also help in dealing with construction wastes. That about the project reuse waste crushedconcrete maters (WCC) from the lath wastage of crushed concrete replacing from coarse aggregate 20%,40%,60%,and 80%.The analysis of demolished crushed concrete aggregate (DCCA) concrete in regular mould cast is to be ready in(7, 14, and 28) days and its mechanical property such as compressive strength, split tensile strength was conducted. The test result show the maximum replacement of DCCA is 60% will give maximum strength to the concrete. The replacing of coarse aggregate uses of waste mater and required strength attain in the conventional M25 grade concrete.
