Abstract

The study presents a replacement of cement by bagasse ash in industrial scale aiming to reduce the carbon dioxide emission into the atmosphere and natural coarse aggregate by recycled coarse aggregates (RCA) due to abundantly available Construction & Demolition waste aiming to preserve natural resources. Bagasse ash(BA) is a byproduct of sugar/ethanol industries abundantly available in the region of Mandya and Mysure and has cementitous properties indicating that it can be used together with cement. In this study bagasse ash were physically and chemically characterized and partially replaced in the ratio of 0%,10%,and 20% by weight of cement to produce bagasse ash based concrete and natural coarse aggregate is replaced by recycled coarse aggregate in the ratio of 25%, 50%, 75% and 100% to produce recycled aggregate concrete(RAC). The optimum level of bagasse ash and recycled coarse aggregate were found and then cast to produce bagasse ash based recycled aggregate concrete. The mix design of all the concrete is done as per IS specifications. The rheological properties of concrete like slump test and hardened properties like compressive strength, split tensile strength were studied. The results shows that strength of the concrete can be increased at the optimum percentage of recycled coarse aggregate and bagasse ash.
