This study investigates the feasibility of using locally available granite powder as a partial replacement for fine aggregate in the production of High-Performance Concrete (HPC) targeting a compressive strength of 60 MPa at 28 days. Concrete mixes were prepared by replacing natural sand with granite powder at varying levels (0%, 25%, 50%, 75%, and 100% by weight). A constant dosage of 1% superplasticizer (by weight of cementitious materials) was used. Mechanical properties were evaluated for different mixes and curing periods. Results indicate that partial replacement of sand with granite powder significantly enhances the mechanical performance of HPC. The optimum replacement level was identified at 22%, achieving the highest compressive strength. The findings support the sustainable use of granite powder as a partial fine aggregate replacement in structural concrete.
