Abstract: The 5% of global CO2 emissions are from cement industries. To reduce these emissions of CO2, there is a necessity for sequestration of CO2 into stable forms. The research focuses on using CO2 as a curing agent. This paper summarizes the mechanical properties of concrete when cured in artificial CO2 environment i.e. by using dynamic pressurized CO2 curing chamber and Dry ice. The research includes designing a concrete mix of M25 grade as per IS 10262:2009. In this research, the effect of carbonation was analysed by CO2 curing and dry ice curing. The experimental study on water cured, CO2 cured and dry ice cured specimens for compressive strength, split tensile strength and flexural strength were carried out. The results show that 90% of compressive strength was achieved for 8 hours of CO2 cured specimens when compared to 28 days of water cured specimens.
Keywords: Cement industry, pollution, CO2 sequestration, carbonation, CO2 curing, dry ice, penetration, compression strength, split tensile strength and flexural strength.
