A Research on Partial Replacement of Fine Aggregate by Waste Foundry Sand

Abstract

Abstract. The by-products from metal casting industries, waste foundry sand is generated in huge amount which causes many pollution to the environment like infertility of sand, unsightliness, awful odour, etc., because of improper disposal. Such kind of environmental problems can be reduced when those wastes are used as building material during concrete production. So, a research work was carried out in concrete containing waste foundry sand in the range of 15% to 25% with 5% increase, as a partial replacement for fine aggregate(M-sand) for M-20 grade concrete. The concrete made of foundry sand in the proposed mix design was tested and compared with ordinary concrete for workability, compressive strength, Flexural strength and Tensile strength. The cubes were tested on 14th and 28th day for mix of 1:1.54:2.97 at a water-cement ratio of 0.45 and the results were carried out with comparison.
