Abstract—Agricultural and industrial by-products are commonly used in concrete production as cement replacement materials or as admixtures to enhance the fresh and hardened properties of concrete as well as to minimize the negative environmental effects. Sugar Cane Bagasse Ash (SCBA) is one of the promising cement replacement materials, which potentially be used as a partial replacement of cement for producing concrete; properties of such concrete depend on the chemical composition, fineness, and burning temperature of SCBA. Approximately 1800 Million tons of sugarcane are annually produced all over the world, which leaves about 40-45% bagasse after juice extraction in sugar mills yielded an average annual production of about 700 Million tons of bagasse as a waste material. In this study the SCBA was incorporated in concrete from 5% to 50% by weight of cement. Effect of SCBA on workability, compressive strength, splitting tensile strength and bond strength of concrete was investigated. The results showed that incorporation of SCBA in concrete as partial replacement for cement up to 30% significantly enhanced the mechanical properties of concrete.
