Abstract
The study on the effect of Granite Dust and M Sand on Concrete evaluates the impact of using granite dust and M sand as partial replacements for natural sand in concrete. Through a series of experimental investigations, the researchers assess the optimal percentage of replacement for these materials by conducting compressive strength tests on cube and cylindrical specimens. Additionally, reinforced concrete beams are cast using the blended fine aggregate to analyze their behavior under flexural loading. The study includes determining ultimate strength, load-deflection characteristics, crack patterns, ductility, and flexural rigidity of the concrete beams. The outcomes are compared with control concrete beams to draw conclusions on the feasibility of substituting natural river sand with granite dust and M sand in concrete production. An experimental investigation has been carried out to explore the possibility of using the granite Dust, and M Sand as a partial replacement of sand in concrete. Total twenty-seven cubes and nine beams of concrete with Granite Dust (GD), and M Sand (MS) were prepared and tested. The percentages of Granite Dust (GD), and M Sand (MS) added to replace sand were 5%, 10%, 15%, 20%, 25% and 30% of the sand by weight. It was observed that substitution of 15% of sand by weight with granite Dust in concrete was the most effective in increasing the compressive and exural strength compared to other ratios. The test resulted showed that for 15% ratio of GP in concrete, the increase in the compressive strength was about 25% compared to normal concrete. Similar results were also observed for the exure. It was also observed that substitution of up to 20% of sand by weight with M Sand in concrete resulted in an increase in compressive and exural strength of the concrete.
