In this Experimental study, steel slag is used as coarse aggregate replacement Material up to 100% and Fly ash is
used as Partial replacement for cement up to 30%. Class C Fly ash is used as partial cement replacement material. The steel
Slag aggregate percentage replacement is 100% and fly Ash replacement percentage are 10%, 20%, 30% by weight of cement.
Tests are conducted in cubes, cylinders and prisms to find out the compressive strength, split tensile strength and flexural
strength for both Ordinary concrete and steel slag concrete with partial replacement of fly ash. This project report
summarizes the experimental program to investigate the significance of steel slag aggregate & partial replacement of fly ash in
concrete. Finally suggestions were made for the use of steel slag with partial replacement of fly ash for cement to increase the
strength of concrete.
