Abstract: Undoubtedly concrete is the most versatile and widely used construction material. It is the material of choice with strength, performance and durability. This study aims at utilization and to ascertain the suitability of saw dust ash as a partial replacement of cement, glass powder as a partial replacement of fine aggregate and rubber tyre pieces as a partial replacement of coarse aggregate in normal M30 grade concrete. Initially, all trial combinations were casted by replacing binder, fine aggregate and coarse aggregate at a varying rate of 2 to 10 %. The replacement percentage of binder giving maximum strength is chosen and is fixed accordingly for further studies. Thereafter, the percentage of coarse aggregate and fine aggregate were changed from 2 to 8% to arrive at an optimum mix having maximum compressive strength. The strength performance of these concrete with normal concrete mix is investigated and findings are reported.
