Abstract : Cement manufacturing is an energy intensive process and consumes lot of raw materials from limited natural resources. Cement clinker production contributes 5-6 % of global CO2 emissions. Because of technology advancement and environmental concerns, Portland pozzolana cement is widely produced instead of ordinary Portland cement by blending solid waste materials and industrial by-products as supplementary cementitious materials. A number of by-products are available in enormous quantities and can be used for blended cement production to achieve durable and sustainable concrete. A systematic evaluation study needs to be carried out to find potential use of new supplementary cementitious materials to achieve suitable energy-efficient processing methodologies. Sugarcane bagasse ash is obtained as a by-product from cogeneration boilers in sugar industries and directly disposed to the nearest land. The utilization of bagasse ash has been constrained because of inadequate understanding of the material. This paper describes a study that involves evaluation of pozzolanic performance of sugarcane bagasse ash for use as a supplementary cementitious material. Performance evaluation of bagasse ash blended concrete and comparison with fly ash blended concrete are discussed in the paper. The results from this study show that use of sugarcane bagasse ash in concrete significantly enhances its performance compared to control and fly ash blended concrete.
