Abstract: Waste disposal in environment due to rapid urbanization and industrialization is increasing day by day. Disposal of wastes in the environment is more difficult in the construction industry. Marble powder and quarry dust are the waste materials obtained from the dressing and processing unit of marble production and quarries respectively. These waste materials are dumped in the environment as a landfill, and they can be used as a viable substitute material to the ingredients of concrete to a great extent. This will result in the production of economically green concrete; this happens because of less usage of river sand, leading to reduction in damage to to the environment. In this paper, natural sand used in the fiber-reinforced concrete (FRC) of grade 20 was replaced by varying proportions (0%, 25%, and 50%) and combinations of quarry dust (QD) and marble powder (MP) with 0.5% of basalt fiber added to the mix in order to explore the impact of QD and MP on the mechanical properties of concrete. The strength properties were assessed at 3rd, 7th, 14th and 28th day and the obtained results are tabulated. It is observed that a particular proportion of QD and MP enhances the strength of FRC.
