The increasing demand and scarcity of construction materials like cement and aggregates make the researches all over the world nowadays to focus on finding ways of utilizing industrial wastes and demolished wastes as source of raw materials and eco-friendly alternatives for concrete ingredients. Using recycled aggregates in concrete leads to preservation of the environment and promotes sustainable development. Recycled aggregate is obtained after crushing and screening of the construction rubble from tested laboratory specimens like cubes and cylinders. Sugarcane bagasse ash, the by-product of Sugarcane is the most fibrous material and contains alumina and silica. Bagasse ash used not only to reduce consumption of cement, cost of making concrete and pollution of the environment but also consumes the excess calcium present in the cement improving the durability related properties of concrete. In this work, mix design for conventional M20 grade concrete is made. Based on the literature survey, conventional coarse aggregate is partially replaced by 30% with recycled coarse aggregate. In this 30% recycled aggregate contained concrete, cement is partially replaced by 0, 5, 10, 15 and 20% with Sugarcane bagasse ash. Experimental study was carried out to investigate the mechanical properties. Based on the test results, the optimum replacement level of cement with Sugarcane bagasse ash is observed as 15% for overall efficiency.
