An Experimental Study on Partial Replacement of Fine Aggregate by Quarry Dust and Granite Powder in M25 Grade Concrete
Concrete is the most widely used construction material in civil engineering industry because of its high structural strength and stability. For low- and middle-income people very difficult to construct the buildings. Now-a-days, in the market the fine aggregate rates are increasing rapidly due to the depletion of River sands. Quarry Dust and Granite Powder are among the powder wastes generated by the industry. To overcome from this crisis, partial replacement of fine aggregate by quarry dust and granite powder in concrete. This research is carried out in two phases. In the first phase, the mix of M25 cubes is made by normal convectional concrete to determine the maximum compressive strength. In the second phase, Fine aggregates is partially replaced by Quarry Dust and Granite Powder by 50%, 60% and 50%,40% as fine aggregates as constant to determine the compressive strength as 3,7 and 28 days. This research evaluates the strength and strength efficiency factors of hardened concrete by partially replacing of fine aggregates by various percentages of Quarry Dust and Granite Powder for M25 grade of concrete at different ages.
