Concrete, a vital construction material, is composed of fine and coarse aggregates bound together by a cement paste. While Portland cement is commonly used, alternative hydraulic cements like calcium aluminates cement find occasional application. However, Portland cement, the second most environmentally harmful component in concrete after water, faces challenges such as resource scarcity and durability issues. To address these challenges, additives known as admixtures have emerged.This study investigates the efficacy of chemical and mineral admixtures, including rice husk ash (RHA) and graphene oxide (GO), in enhancing concrete performance. RHA and GO, derived from industrial by-products and carbon materials, respectively, offer promising prospects for improving concrete properties while mitigating environmental impacts. The study examines their impact on concrete characteristics such as compressive strength, flexural strength, and durability.This study investigates the efficacy of incorporating graphene oxide (GO) and rice husk ash (RHA) into concrete mixtures to enhance their strength and suitability for construction applications. Experimental testing reveals that concrete compositions containing 15% RHA and 2.5% GO exhibit improved compressive strength, modulus of elasticity, flexural strength, and split tensile strength compared to control mixes. The addition of 15% RHA and 2.5% GO results in a maximum compressive strength of approximately 49.80 MPa, with subsequent decreases in strength observed with higher RHA content. Similarly, flexural strength peaks at approximately 29.88 MPa for the same composition but decreases with higher RHA content. Split tensile strength reaches a maximum of approximately 6.07 MPa for the 15% RHA and 2.5% GO mixture, with a decline observed beyond 15% RHA content.
