摘要：The demand for sand is the major problem for conventional construction recently. We need a best alternateconstruction material to fulfill the sand demand. In this paper we presents the results of an experimental investigationcarried out to evaluate the mechanical properties of concrete mixtures in which fine aggregate (sand) was partially replacedwith fly ash, copper slag and granite powder using M30 grade concrete. Fine aggregate (sand) was replaced with fourdifferent percentages (0%, 25%, 50% and 75%) of fly ash, copper slag and granite powder by weight. Tests were performedfor properties of fresh concrete. Compressive strength, split tensile strength were determined at 7, 14 and 28days. Testresults indicate significant improvement in the strength properties of plain concrete by the inclusion of above mentionedindustrial waste as partial replacement of fine aggregate (sand) and it can be effectively used in structural concrete.Concrete is an artificial conglomerate stone made essentially of Portland cement, water, sand and coarse aggregates. Themixture of the materials results in a chemical reaction called hydration and a change in the mixture from plastic to a solidstate. The worldwide consumption of sand as fine aggregate in concrete production is very high, and several developingcountries have encountered some strain in the supply of natural sand in order to meet the increasing needs of infrastructuraldevelopment in recent years. A situation that is responsible for increase in the price of sand, and the cost of concrete.
