Every year the consumption of concrete is increasing due to rapid growth in infrastructure. Concrete is extremely versatile and is used for all types of structures. Traditionally, river sand has been the preferred material for making concrete. However, with its continuous use and ever increasing consumption, the sources of sand are dwindling globally. As a result, restrictions are being put in place by various governmental agencies, with a view to preserve the ecology and environment. This has brought in severe strains on the availability of sand forcing the construction industry to look for alternative materials. The present investigation aims in the study of properties of concrete in which quarry dust is used as a partial replacement for natural sand. The basic strength properties of concrete were investigated by replacing natural sand by quarry dust at replacement levels of 10%, 15%, 20%, 25%, 30%, 35%, 40% and 50% for mix design of M30. In the hardened state compression strength test, split tensile of quarry dust concrete as well as normal concrete were performed at 3,7and28 days that demonstrates maximum strength. As the properties are good as sand, the quarry dust is used as fine aggregate in replacement with sand in the cement concrete. Sieve analysis helps to determine the particle size distribution of the coarse and fine aggregates. It is found that 30% and 35% replacement of fine aggregate by quarry dust gives maximum result in strength than normal concrete and then decreases from 40% and 50%. The compressive strength is quantified for varying percentage and grades of concrete by replacement of sand with quarry dust.
