The experimental investigation was conducted to identify the suitability of recycled the demolished concrete waste as coarse aggregate in normal concrete. This research involved partial replacement of coarse aggregate by the demolished waste material in the M30 grade concrete. The percentage replacements of coarse aggregates by the recycled coarse particles respectively were 25%, 50%, 75%, 100%. The properties of coarse particles from demolished concrete waste were studied and compared to the normal aggregates used in normal concrete.In this project, to investigate the mechanical properties of concrete like workability, setting time of fresh concrete, compressive strength, Split tensile of hardened concrete, flexural strength of concrete. From the result, the compressive strength the compressive strength is 15% more than the conventional concrete. The maximum split tensile strength is attained at the same replacement level mentioned above. From the result, the split tensile strength the compressive strength is 7.5% more than the conventional concrete. The maximum flexural strength is attained at the same replacement level mentioned above. From the result, the flexural strength is 5% more than the conventional concrete. From these results, that the recycled concrete was more effective than the conventional concrete. Large scale recycling of demolished waste and concrete will offer not only the solution of growing waste disposal problem, but it will also help to natural resources for meeting increasing demand of aggregates for construction purposes. By using this debris concrete as the replacement material, we can imply the highly sustainable environment in construction industry worldwide
