Abstract: The construction industry seeks high-performance mortar for strong and stable structures. However, industrial by-products like Sugarcane Bagasse Ash (SCBA) and Ground Granulated Blast Furnace Slag (GGBS) pose environmental and health concerns due to disposal issues. Interestingly, incorporating SCBA and GGBS into mortar can enhance its properties, such as water permeability and strength. This study aims to investigate the mechanical and durable properties of mortar using SCBA and GGBS as partial cement replacements, promoting sustainable construction practices. Five mortar mixes were prepared with varying SCBA content (5%, 10%, 15%, and 20%) and a constant GGBS content (30%). The samples were cast into 50x50x50 mm cube and 160x40x40 mm beam, cured for 7, 28, and 56 days, and then evaluated for their hardened properties and quality.

Keywords: Mortar, Mechanical and Durable properties, Industrial waste.
