This experimental work describes the reuse of used foundry sand (cast iron at foundry industries) as a partial replacement to fine aggregate in different percentages that can be adopted in concrete along with normal river sand designed to meet the requirements of concrete grades of M20 and M30. The foundry sand causes environmental problems because of its improper disposal. Continuous technological and industrial developments are taking place, and also the rate of generated waste products is increasing. In construction industries, demand for construction materials are never coming down, and that is why there is a need to focus on different construction materials. The waste material like foundry sand is used as a construction material; it can help to reduce the amount of disposal material. Foundry sand can be used as a partial replacement of fine aggregate. The fine aggregate has been replaced by used foundry sand accordingly in the range of 0%, 25% and 50% for M-20 and M-30 grade concrete. These tests were carried out to evaluate the compressive strength of molds of size 150 x 150 x 150 mm for 7 days and 28 days. As a result, the compressive strength increased up to 25% addition of used foundry sand, and it shows decrees in compressive strength for 50% replacement of fine aggregate by foundry sand.
