METHOD FOR PRODUCING CURED BODY
To provide a method for producing a cured body capable of producing a cured body having sufficient strength without requiring high molding pressure.SOLUTION: There is provided a method for producing a cured body which comprises: a first step of producing a compact by pressurizing and molding a composition containing CaO, SiO2 and Al2O3 and having a hydroxylation degree of 15 to 26 mass%; a second step of bringing the compact prepared in the first step into contact with an aqueous bicarbonate solution prepared by blowing carbon dioxide gas into a mixed liquid of a material containing a Group 2 element and water; and a third step of drying the compact after the second step.SELECTED DRAWING: None
【課題】高い成形圧力を要せずとも、十分な強度を有する硬化体を製造可能な硬化体の製造方法を提供すること。【解決手段】ＣａＯ、ＳｉＯ2及びＡｌ2Ｏ3を含む組成物であって、水酸化度が１５～２６質量％である組成物を加圧成形して成形体を作製する第１の工程と、第２族元素含有材料と水との混合液に炭酸ガスを吹き込んで調製した炭酸水素塩水溶液と、第１の工程で作製した成形体とを接触させる第２の工程と、第２の工程後の成形体を乾燥する第３の工程を含む、硬化体の製造方法。【選択図】なし
