AbstractThe consistency in the quality of as-such received sugarcane bagasse ash (SCBA) samples produced from the sugar industry throughout the sugarcane crushing period is a crucial aspect from the pretreatment point of view for their use in cement-based products. The majority of the reported research used SCBA samples collected from a single source (sugar plant) and at one time. In view of these unattended facets of SCBA, an organized study (characterization and pozzolanic reactivity through various techniques) in a holistic manner was conducted on as-such received SCBA samples collected from two sugar industries having distinct ash collection systems at frequent intervals throughout the sugarcane crushing period to deduce profound conclusions about the reactivity of SCBA in a particular sugarcane crushing period. The results of this study indicate that the physical and chemical characteristics of as-such received SCBA samples collected from a specific sugar industry in a particular crushing period differed to a reasonable extent. For assessment of the pozzolanic nature of the SCBA samples, it is desirable to perform a strength activity index along with the Frattini test. Based on the study, a simple framework was proposed for assessing the variability in the quality of as-such received SCBA.
