Abstract: India is modernizing its infrastructure at a fast pace and concrete is an essential requirement of infrastructural development. The main constituents of concrete are cement, sand (fine aggregate), gravel (coarse aggregate) and water. The high consumption of natural resources like sand and gravel affects the sustainable development. The study aims to determine the maximum percentage of waste foundry sand (WFS) for partial replacement of fine aggregate in concrete for different ratios (5%, 10%, 15%, 20%, 25%, 30%, 35% and 40%) by conducting strength tests on hardened concrete such as compressive strength, split tensile strength and flexural strength. From the durability point of view, tests such as acid resistance and alkalinity measurement are conducted. The strength and durability properties of concrete containing WFS indicate that there is a significant increase in mechanical strength for 35% sand replacement. The basic principle that the industrial waste by-products can be successfully used as building materials, thereby minimizing or eliminating the environmental degradation by way of hiding the same within a building structure has been test verified with WFS and has promising replacements for the conventional fine aggregate in the concrete.
