Studies on the utilization of residual sugarcane bagasse ash (SCBA) from high-temperature cogeneration boilers in concrete are limited. This study explored the pretreatment and optimization of SCBA collected from high-temperature boilers through various physicochemical methods. The research revealed that SCBA can be used as a supplementary cementitious material with minimal processing efforts, and a 15% replacement level is suggested as optimal for SCBA-blended cement. Additionally, a framework with step-by-step procedures including pretreatment and optimization methods is proposed for the use of SCBA based on the investigation.
Studies on the characterization and performance of residual sugarcane bagasse ash (SCBA) obtained from high-temperature cogeneration boilers in concrete are highly limited. This study investigated the pretreatment process and optimization of SCBA collected from high-temperature boilers by various physicochemical methods. The effect of recalcination and grinding on the physical and mineralogical properties of SCBA were also examined. The percentage replacement of cement with SCBA was optimized using packing density and flow. The performance of optimized binder with combinations of cement and SCBA was validated through compressive strength of mortar specimens. From the results, it was observed that SCBA from high-temperature boilers can be used as a supplementary cementitious material with minimal processing efforts, and a 15% level of replacement is suggested as the optimum level for SCBA-blended cement. Based on the investigation, a framework with a step-by-step procedure including pretreatment and optimization methods is suggested for the use of SCBA.
