Portland cement, renowned as the cornerstone of concrete, is a versatile yet relatively costly material. However, large-scale cement production presents a dual threat to the environment, causing ecological damage and eliminating essential natural resources. In response to these pressing concerns, researchers have turned to industrial byproducts as supplementary cementitious materials to mitigate the environmental impact. This study's main goal was to investigate the mechanical properties of concrete by partially replacing cement (OPC-53grade) with rice Husk Ash (RHA). The research focused on M30 grade concrete, incorporating RHA at varying proportions of 10%, 15%, and 20%. This comprehensive study delved into the compressive and flexural strengths of the concrete at 7 and 28 days of age. Using rice Husk Ash (RHA) as a partial replacement for Portland cement in critical infrastructure projects holds promise for advancing sustainable development in the construction industry. This research highlights the positive impact on concrete mechanical properties, specifically noting a significant increase in compressive strength. This innovation contributes to cost reduction in construction projects and addresses environmental concerns associated with large-scale cement production. Substituting RHA into concrete mixes can promote more resilient and eco-friendly infrastructure, aligning with sustainable development goals.
