dc.description.abstract In this study, sugarcane bagasse ash is recognized as a pozzolan, and the examination delves into its impact on the structural properties and durability of concrete. A signif­ icant volume of bagasse ash is generated annually in Sri Lanka through the recycling of raw bagasse for power generation in the sugar industry. The bagasse ash utilized in this study was procured from a local sugar factory in Sri Lanka. Diverse methods, such as X-ray diffraction, X-ray fluorescence, and laser particle size analysis, were utilized to evaluate the chemical, physical, and mineralogical characteristics of the bagasse ash. Additionally, a scanning electron microscope was utilized to examine the microstructure. The assessment extended to the examination of hardened properties such as compressive strength, bond strength, tensile strength, ultrasonic pulse velocity, and durability properties including water absorption and penetration of chloride. The concrete mixtures were formulated by substituting bagasse ash at ratios rang­ ing from 5% to 20% by weight instead of Portland cement. The local ash demonstrated pozzolanic characteristics as per the results of chemical, physical, and mineral tests. Notably, mixtures containing 5% to 15% bagasse ash substitution were identified as optimum replacements for achieving elevated compressive and tensile strength. Si­ multaneously, the water absorption and rapid chloride permeability test indicated a lower value of up to a 10% ash content percentage than control concrete. en_US
