River sand is widely used for concrete as fine aggregate. The increased cost of river sand and depletion in ground water table due to illegal sand mining leads to find an alternative for fine aggregate without compromising the strength. In this study, concrete mix M30 has been designed using quarry dust and manufactured sand by replacing the river sand. Four mix proportions were made to test the effect of inclusion of quarry dust and manufactured sand in concrete and the results were compared with the control specimens. It was found that the strength of the concrete is enhanced in both the types of replacements.Keywords

The sharp fall in underground water table in river basins is said to be the outcome of indiscriminate sand mining resulting in the deepening of river beds. The natural sand beds have voids of 45-50% in the soil where the rain water is retained by the river sand. This property of the river sand is mainly responsible for maintaining the ground water table in and around river basins. This paper deals with the partial replacement of river sand by fly ash in aggregate in concrete without compromising the strength.- Reduction of Global Warming Gas Emissions from the Manufacture of Portland Cement Using High Volume Fly Ash Concrete
