Abstract: The possibility of replacing fine aggregate with industrial waste products such as waste foundry sand and quarry dust which offers technical and environmental advantages which are of great importance in the present context of sustainability in the construction sector. This study investigated the effect of quarry dust in concrete as partial replacement of fine aggregate in various percentage (0%-25%), on concrete properties such as mechanical (compression strength, split tensile strength, flexural strength) of 28 days curing of m20 grade of concrete as per IS-10262-2019. As the result of quarry dust replacement concrete, we obtain the optimum percentage of quarry dust and fix the value as constant and add foundry sand as partial replacement of fine aggregate in various percentage (0%-25%) in the m20 grade concrete. And we are going to test the compression strength, split tensile strength, flexural strength of 7days and 28 days curing of cement concrete to determine the strength of concrete. This study increase the use of industrial waste material.
