Sugarcane is one of the main cash crop grown in around 115 countries. The waste produced after its use as raw material is dumped on open lands. Detail estimation of sugarcane bagasse ash (SCBA) production on basis of sugarcane production all over as well as mainly in India is carried out in this study. Use of SCBA as a supplementary cementitious material adds sustainability to concrete by reducing the CO2 emission during cement production. The positive effects of SCBA as a partial replacement of cement on the mechanical properties of concrete are recognized through different researches; however, the overall improvement depends on the durability properties of SCBA in cementitious medium. In this study, durability properties of conventional concrete utilizing SCBA sourced from sugar factory site have been investigated. Concrete mixtures with SCBA content ranging from 0% to 30% of total binder were used. The compressive strength, ultrasonic pulse velocity and loss in weight of the concrete specimens were determined after exposure to sodium hydroxide solution. The reactivity of alkali with mixes containing SCBA in terms of expansion was determined by accelerated as well as Indian standard test method. The results demonstrated that incorporation of SCBA as partial replacement of cement improved the resistance to alkali attack on concrete. The SCBA in cement aggregate mix showed reduction in expansion proving the effectiveness of waste SCBA inclusion in cementitious medium.
