METHOD FOR FIXING CARBON DIOXIDE AND METHOD FOR PRODUCING CEMENT ADMIXTURE
To provide a method for efficiently fixing CO2 in a hardened cementitious body.SOLUTION: A method for fixing carbon dioxide in a hardened cementitious body includes a carbon dioxide fixation process of contacting a mixture containing a hardened cementitious body and water with carbon dioxide-containing gas. The carbon dioxide fixation process is carried out while adding water to the mixture on the basis of, a preliminarily calculated water evaporation rate in the process, and while maintaining a water content in the mixture within a range of 80 to 150 mass% of the water content that is preset in a solid-liquid ratio range of 0.1 to 0.5.SELECTED DRAWING: Figure 4
【課題】セメント質硬化体にＣＯ２を効率よく固定化する方法を提供すること。【解決手段】セメント質硬化体へ二酸化炭素を固定化する方法であって、前記セメント質硬化体と水とを含む混合物に二酸化炭素を含むガスを接触させる二酸化炭素固定化工程を備え、前記二酸化炭素固定化工程が、予め算出した当該工程における水分蒸発速度に基づいて前記混合物に加水しながら、前記混合物における水分量が、固液比で０．１～０．５の範囲で予め設定された水分量の８０～１５０質量％の範囲内に保たれつつ行われる、方法。【選択図】図４
