In this study Waste foundry Sand, which is a waste product of foundry industry is used. Waste Foundry Sand is used as partial replacement of fine aggregate in concrete. As the natural sand is used as fine aggregate and it is a material which is adversely affecting our environment. Hence, therefore a focus has been made on the replacement of the natural sand in the concrete in this study. In this study the Waste Foundry Sand has been used as the fine aggregate in the concrete. A number of samples are prepared with different percentages of Waste Foundry Sand in the Concrete. In total five samples were prepared as S-1, S-2, S-3, S-4 and S-5 having the percentage Waste Foundry Sand as 5%, 10%, 15%, 20% and 25% w.r.t to weight of fine aggregate. A number of tests have been performed on the concrete samples in order to examine the strength properties of the concrete which includes tests such as Compressive strength test, split tensile test etc. After the test it was observed that both the strengths increase as we increase the percentage of Waste Foundry Sand in the concrete. But this increase was observed up to a certain limit after that the strength starts reducing. Thus, giving us the maximum value at certain percentage of waste foundry sand.
