In the present study an investigation is made on properties of concrete by partial replacement of Cement with Ground Granulated Blast Furnace Slag (GGBS) and Fine Aggregate with Quarry Dust (QD). Ground Granulated Blast Furnace Slag is a byproduct of Iron and Steel industry which is produced in large quantities as a solid waste. It is highly cementitious, Quarry Dust is used as a replacement of Natural Sand due to its scarcity. The replacement percentages of Cement with GGBS are 20%, 40% and 60% by weight and 25%, 50%, 75% and 100% of Quarry Dust are used as a replacement of Natural Sand. Various combinations of GGBS and Quarry Dust were prepared using M30 Grade of Concrete. The effect on these replacement materials on Compressive Strength, Split Tensile Strength, Flexural Strength, Modulus of Elasticity and Water Absorption were studied and the results obtained were compared with the Control Concrete. It is observed that the optimum replacement percentages of GGBS and Quarry Dust are 40% and 50% respectively.
