This study looks into using local materials to improve concrete by replacing some of its traditional components. Specifically, it examines how rice husk ash (RHA) can partially replace pozzolanic Portland cement (PPC) and how glass powder waste can substitute sand. The goal is to find the best combination that strengthens RCC beams for concrete grades M35 and M40. This research also tackles the issue of managing agricultural waste, such as rice husks, and addresses the growing concern over glass waste, which is increasing due to high production rates and slow decomposition. By reducing cement use, the goal is to minimize the environmental impact, as cement production uses a lot of raw materials and releases harmful gases. The primary focus is on determining the optimal amount of glass powder waste that can replace sand in concrete, as it has excellent pozzolanic properties. Additionally, the study looks at how RHA, a local biodegradable material, can replace part of the PPC. Ultimately, this project seeks to find effective solutions for managing agricultural and glass waste while promoting more sustainable construction practices.
