Effect of Copper Slag, Fly Ash and Granite Power as a Partial Replacement in Fine Aggregate
The demand for sand is the major problem for conventional construction recently. We need a best alternate construction material to fulfill the sand demand. In this paper we presents the results of an experimental investigation carried out to evaluate the mechanical properties of concrete mixtures in which fine aggregate (sand) was partially replaced with fly ash, copper slag and granite powder using M30 grade concrete. Fine aggregate (sand) was replaced with four different percentages (0%, 25%, 50% and 75%) of fly ash, copper slag and granite powder by weight. Tests were performed for properties of fresh concrete. Compressive strength, split tensile strength were determined at 7, 14 and 28days. Test results indicate significant improvement in the strength properties of plain concrete by the inclusion of above mentioned industrial 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. The mixture of the materials results in a chemical reaction called hydration and a change in the mixture from plastic to a solid state. The worldwide consumption of sand as fine aggregate in concrete production is very high, and several developing countries have encountered some strain in the supply of natural sand in order to meet the increasing needs of infrastructural development in recent years. A situation that is responsible for increase in the price of sand, and the cost of concrete.
