Abstract

Metal foundries use large amounts of sand as part of the metal casting process. Foundries successfully recycle and reuse the sand many times in the casting process. When the sand can no longer be reused in the foundry, it is removed from the foundry and is termed as foundry waste sand. The generation of waste foundry sand as a byproduct of metal casting industries causes environmental problems because of its improper disposal. Thus, its usage in building material, construction, and other fields is essential for the reduction of environmental problems. Like many waste products, foundry sand has beneficial applications to other industries. Foundry sand consists primarily of silica sand, coated with a thin film of burnt carbon, residual binder (bentonite, sea coal, resins) and dust. Foundry sand can be used in concrete to improve its strength and other durability factors. Foundry sand can be used as a partial replacement of cement or as a partial replacement of fine aggregates or total replacement of fine aggregate and as a supplementary addition to achieve different properties of concrete. This research is carried out to produce a low-cost and eco-friendly concrete. This work demonstrates the use of waste foundry sand as a partial replacement by fine aggregate in concrete. An experimental investigation is carried out on a concrete containing waste foundry sand in the range of 0%,10%,20%,30% 40%, and 50% by weight for M-25 grade concrete (PCC). Material was produced, tested, and compared with conventional concrete in terms of workability and strength. These tests were carried out on a standard cube of 150*150*150* mm for 7, 14, and 28 days to determine the mechanical properties of concrete. Through experimental results the variation of compressive strength with the partial replacement of waste foundry sand can be found out. This work aims to know the behavior and mechanical properties of concrete after the addition of industrial waste in different proportions by tests like compressive strength.
