BURNED PRODUCT, HYDRAULIC COMPOSITION, CEMENT COMPOSITION, AND METHOD FOR PRODUCING BURNED PRODUCT
To provide a hydraulic composition and the like, capable of allowing a produced hydrate to absorb more carbon dioxide by speeding up hydration of cement-hardened body in the early stages of a material age (one day of a material age), thereby reducing a total emission of carbon dioxide.SOLUTION: A burned product of this invention comprises, based on 100 pts.mass of 2CaO SiO2, 20 to 40 pts.mass of 3CaO Al2O3; and 10 to 100 pts.mass in total of 2CaO Al2O3 SiO2 and 4CaO Al2O3 Fe2O3. The burned product of this invention preferably comprises 0 to 210 pts.mass of 4CaO Al2O3 Fe2O3 based on 100 pts.mass of 2CaO Al2O3 SiO2.SELECTED DRAWING: None
【課題】本発明は、材齢初期（材齢１日）のセメント質硬化体の水和を速めることにより、生成した水和物に、より多くの二酸化炭素を吸収させて、二酸化炭素の総排出量を低減できる水硬性組成物等を提供する。【解決手段】本発明の焼成物は、２ＣａＯ・ＳｉＯ２１００質量部に対し、３ＣａＯ・Ａｌ２Ｏ３を２０～４０質量部、並びに、２ＣａＯ・Ａｌ２Ｏ３・ＳｉＯ２および４ＣａＯ・Ａｌ２Ｏ３・Ｆｅ２Ｏ３を合計で１０～１００質量部含む。また、本発明の焼成物は、好ましくは２ＣａＯ・Ａｌ２Ｏ３・ＳｉＯ２１００質量部に対し、４ＣａＯ・Ａｌ２Ｏ３・Ｆｅ２Ｏ３を０～２１０質量部含む。【選択図】なし
