摘要
运用扫描电子显微镜 (SEM)研究了高游离氧化钙 (f- Ca O)水泥的水化及其在水泥石中氢氧化钙的分布和显微结构特征。讨论了水化早期和后期 Ca(OH) 2 晶体的结晶特性及界面结合关系 ,指出了熟料中成大堆分布的 f- Ca O晶体缓慢水化导致 Ca(OH) 2
By using scanning electron microscope (SEM) the hydrate of highly free-calcium oxide (f-CaO) cements is studied, and the distribution and crystalline characteristics of calcium hydroxide in cement are investigated and the different boundary characteristics between calcium hydroxide with CSH at early hydration stage and later as well. The slow hydrate of f-CaO crystals distributed as big-piles in cement clinker results in the constant growing of Ca (OH)2 crystals. This is the main reason for that the cement stability is not certificated.
