Utlization of Sugarcane Bagasse Ash in Concrete as Partial Replacement in Cement
Bazil Javaid Wani
Abstract: As we all are aware about the growing demand of concrete as important material being used in construction industry. Natural resources are reducing day by day, huge amount of energy being consumed and environmental degradation are involved in the production of cement has motivated researchers to investigate the suitable alternatives to partially or fully replace the cement. The research performed from more than 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. This research examines the suitability of sugarcane bagasse ash used as partial replacement of concrete. Grade of concrete M20 is carried out in accordance with the recommendations of IS: 10262-2009. The cement was partially replaced by SCBA at 5%, 10%, 15%, 20%. The mixes then prepared were checked for the workability by slump test. It was concluded that SCBA increases the workability of the cement concrete. From the results we can conclude that optimum amount of sugarcane bagasse ash that can be replaced with cement concrete is 10% by weight without any admixtures.
