The mechanical properties of concrete are investigated using varying amounts of granite dust and granite chips as a partial replacement for traditional cement and coarse aggregate. In this article, the cubes, cylinders and beams were casted by combining different versions of granite chips and dust as a substitute for conventional aggregates and cement for various concrete grades. Various ratios of granite dust and chips were replaced with conventional concrete, such as 4%, 10% and 15%. To determine the best water cement ratio for M30 and M40 grade concrete, workability test was performed. It was observed that a 0.45 w/c ratio generates a greater compressive strength. These specimens were cured in water for a particular amount of time before being tested in the laboratory for compressive, flexural, and split tensile properties. The obtained results of the tests were compared to other conventional concrete. The modified concrete may be applicable to non-load bearing structures such as kerbs, dividers, and so on. This study examines the feasibility of using Granite dust and chips to improve concrete properties such as compressive, split tensile and flexural strength.
