Abstract
--This study is a part of comprehensive program wherein experimental investigations have been carried out to evaluate the effect of partial replacement of coarse aggregate by Construction and Demolition(C&D) Waste on compressive strength, tensile strength and workability of RAC (Recycled Aggregate Concrete). The main objective of this investigation is to find out up to what percentage the Natural Coarse Aggregate (NCA) can be replaced by Recycled Coarse Aggregate in the concrete mix for an equivalent application or purpose. So in this study we have taken the demolished concrete aggregate 10%, 20%, and 30% by weight of the conventional coarse aggregate and the concrete cubes were casted by Recycled Aggregate Concrete. Then further tests conducted such as Workability test, Compressive strength test and Split tensile test for that DAC at the end of 7 days and 28 days curing period. For the strength characteristics, the result showed a gradual decrease in Workability, Compressive strength and Split tensile strength as the percentage of recycled aggregate is increased.
