Abstract

 The amount of CO2 absorbed in cementitious materials using blast furnace slag and γ-2CaO·SiO2 partially instead of cement and carbonation curing was evaluated by various analytical methods. As a result, it was shown that inorganic carbon analysis is more suitable than thermal analysis to evaluate the amount of CO2 absorption in concrete. In addition, it was shown that the concrete using blast furnace slag and γ-2CaO·SiO2 can absorb large amount of CO2 during carbonation curing. Furthermore, it was confirmed that porosity and compressive strength of the concrete equal to or higher than those of ordinary concrete can be obtained by improving the reaction of blast furnace slag due to the high temperature during carbonation curing and densifying the pore structure due to carbonation of γ-2CaO·SiO2.
