Rice husk burning and coal-fired power plant emissions cause a slew of environmental issues. The recycling of rice husk ash (RHA) and fly ash (FA) from power plants as reactive materials for the production of sustainable (green) concrete is discussed in this study. The goal of this study is to see how effective RHA and FA replacement ratios are on the fresh and hardened properties of concrete mixtures. For each recyclable material, the replacement ratio from the cement content was 30%. (10% RHA and 20% FA). The drop of freshly poured concrete was determined. The compressive strength and bond strength of hardened concrete were also studied as mechanical properties. The compressive strength was measured at 7 and 28 days. The water permeability of cured concrete was tested as a physical property. When compared to the control combination, test showed that the RHA and FA improved mechanical and physical qualities. The cementitious concentration of 450 kg m3 produced better results than the other materials used. The replacement ratio of 30 percent cement by 10% RHA and 20% fly ash, in particular, resulted in enhanced mechanical characteristics. The water permeability of all combinations reduced as the cementitious concentration increased due to the decrease in air content. As the cementitious content reduced, the water permeability loss ratios improved.
