Utilization of sugarcane bagasse ash as cement replacement for the production of sustainable concrete - A review

Concrete is one of the important material being used in construction industry. Rapid reduction of natural resources, huge amount of energy consumption, and environmental degradation involved in the production of cement has motivated researchers to investigate the suitable alternatives to partially or fully replace the cement. The research performed over the last two decades concerning the use of Sugarcane Bagasse Ash (SCBA) as a cement replacement to produce structural concrete is summarized in this paper. Firstly, general information about SCBA production, effect of burning temperature on the SCBA structure, physical and chemical properties of SCBA and reaction mechanism of SCBA are briefly discussed. Then, the influence of SCBA on the fresh state properties is presented and finally, the hardened state characteristics i.e. strength and rate of strength gain, modulus of elasticity, chloride ion penetration and aggressive environment effect on SCBA concrete are presented.
