EFFECT ON CO2 CURED CONCRETE EXPOSED TO MAGNESIUM SULPHATE

This research presents the use of sugarcane bagasse ash to produce high strength in concrete. Cement is replaced with 5% and 15% and 25% by SCBA and 10% silica fume. Present research focuses on CO2 being used in construction practice. This report summarizes the potential of CO2 cured concrete when exposed to Sulphates. To verify the durability of concrete, an environment is created for the specimens. In this study the effect of CO2 curing was checked by dry ice curing and CO2 gas curing. The concrete samples are cured in water and tested for 28 days, 90days and 120days. The concrete samples are cured in CO2 and Dry ice for 8hours and they are immersed in 2% Mgso4 for 28 days, 90days and 120days and tested for mechanical properties. The performance of dry ice and CO2 cured specimens are compared with specimens cured in water.
