摘要

Problem to be solved: to provide a method of manufacturing a tobermorite containing building material containing difficult to carbonation.Calcium compound containing at least one of Ca (OH) 2 and CaoSiO2Li2SO4Na2SO4MgSO4At least one kind of sulfate selected from the group consisting of ZnSO4 and (NH4) 2SO4WaterIncludingWhen the total molar number of calcium compound and SiO2 is 0.18 mol, the molar number of sulfate isWhen sulfate is Li2SO4, 0.57 to 1.43 mmolFor Na2SO4, 0.57 to 1.15 mmolFor MgSO4, 0.57 to 2.30 mmolFor ZnSO4, 0.57 to 1.43 mmolIn the case of (NH4) 2SO4, the preparation of the hydrous composition within the range of 0.57 to 2.30 mmol andHydrothermally synthesizing the hydrous composition at temperatures between 160 and 180Manufacturing method of tobermorite containing building material.Diagram
