Title: Experimental Study on Effects of CO 2 Curing Conditions on Mechanical Properties of Cement Paste Containing CO 2 Reactive Hardening Calcium Silicate Cement.
Authors: Kim, Young-Jin; Sim, Sang-Rak; Ryu, Dong-Woo
Abstract: Human survival is threatened by the rapid climate change due to global warming caused by the increase in CO2 emissions since the Second Industrial Revolution. This study developed a secondary cement product production technology by replacing cement, a conventional binder, with calcium silicate cement (CSC), i.e., CO2 reactive hardening cement, to reduce CO2 emissions and utilize CO2 from the cement industry, which emits CO2 in large quantities. Results showed that the carbonation depth, compressive strength increase rate, and CO2 sequestration rate increased as the CSC content increased, suggesting that CSC can be applied as a secondary cement product.
