The study aimed to explore the feasibility of utilizing GP (granite powder), a waste material from granite cutting processes, as a partial replacement for fine aggregate in concrete. The main objective was to investigate its impact on concrete properties, particularly compressive strength. The research involved conducting a series of experiments with varying percentages of GP replacement (0, 10, 20, 30, 40, and 50%) to determine the optimal replacement ratio. Concrete mixes were prepared according to the specified proportions, and the beams were cast and cured for a designated period. The results revealed that the incorporation of GP into concrete showed significant promise. Particularly, when 20% of the fine aggregate was replaced with GP, the concrete exhibited notable enhancement in compressive strength without compromising structural integrity. This finding not only highlights the potential for utilizing granite waste but also contributes to sustainable construction practices by recycling and repurposing industrial by-products. The study’s outcomes suggest that partial replacement of fine aggregate with GP offers an environmentally friendly solution, reducing waste generation from the granite cutting industry. It also promotes resource optimization and sustainable practices in the construction sector. The positive results at 20% replacement open up opportunities for further research and optimization to identify the most suitable replacement percentages for specific construction applications.
