Abstract

This paper is carried to Cost Optimization by utilization of waste material (Foundry sand). In Metal industries the metal foundries uses large amount of sand as part of the metal casting process. Foundries satisfyingly reclaim and reuse the sand many times in casting process. When the sand can’t be reused in the foundry, it is removing from the foundry and is called as Waste Foundry Sand. Generation of waste foundry sand as by-product of metal casting industries causes environmental problems because of its improper disposal. Thus it usage in building material, construction and in other fields is essential for reduction of cost & environmental problems. Foundry sand consists primarily of silica sand, coated with a thin film of burnt carbon, residual binder 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. In this paper, Cost optimization by foundry sand over Cement with M-20 mix proportion of 1:1.825:2.85 is investigated at replacement were 10-50% at the interval of 10%, by weight of Cement at different curing periods 7 days, 14 days, 28 days at w/c ratio is 0.5.

Keywords: Compressive strength, Waste Foundry sand, Concrete mix, Cost Optimization
