This document presents a study on concrete with partial replacement of ordinary Portland cement with sugarcane bagasse ash (SCBA) and complete replacement of river sand with manufactured sand (M-Sand) as fine aggregates. Standard specimens of M30 grade concrete with 0.45 water-cement ratio were tested at 3, 7, and 28 days to determine compressive strength, split tensile strength, and flexural strength. Test results found compressive strength increased up to 5% SCBA replacement and decreased with further replacement. 15% SCBA replacement achieved highest split tensile strength while flexural strength decreased with M-sand and SCBA. Results were comparable or favorable to conventional concrete, indicating suitability for structural use in buildings
