Abstract: This study reports the usage of sugarcane bagasse ash (SCBA) and Silica fume as supplementary cementitious material for manufacturing concrete with high performance. Due to this, the agricultural and industrial wastes can be utilized in concrete. Cement is replaced with 0% _10%, _5%, 15%, _20% and _25% by SCBA and _10% of silica fume respectively. The present research focuses on using CO2 as a curing agent. The paper summarizes the mechanical properties of SCBA ternary blended concrete when cured in artificial CO2 environment i.e. by using dynamic pressurized CO2 curing chamber and Dry ice. The results show that 80%, 85% and 83% of the compressive strength, split tensile strength and flexural strength was achieved when the specimens are cured in CO2 curing chamber for 8 hours when compared with the samples that are cured in water for 28days. Further, the results show that 73%, 85% and 63% of the compressive strength, split tensile strength and flexural strength was achieved when the specimens are cured in Dry ice for 8hours when compared with the samples that are cured in water for 28days.
