Abstract: This research concentrates on the determination of feasibility of using Eggshell powder and Fly ash as alternate materials of Cement in concrete and their effects on mechanical properties of concrete. The production of cement produces Green house gasses into the atmosphere which pollute the Environment .To overcome this problem we are replacing cement with eggshell powder and fly ash. As the eggshell powder and fly ash are waste material they can available easily and their cost is also very low compared to the production of same amount of cement. The chemical composition of Eggshells is roughly 95% similar to that of cement, which has more calcium content; both physical and chemical properties of cement are almost similar to that of Fly ash. By replacing cement with these two materials in the concrete we can reduce the cost of production of cement and can safeguard the environment. The specimens were prepared and tested for compressive strength, Slump cone test, splitting tensile strength, Modulus of elasticity and flexural strength at 7,14, 28 & 56 days. Results show that the strength of conventional concrete is less than compared to the concrete prepared by replacing the cement with eggshell powder and fly ash.
