摘要
经ＸＲＤ证实永城煤矸石是砂质泥岩。其主要粘土矿物是高岭石，但加热相变有别于纯净的高岭石。当煅烧温度９００℃时，活性来自偏高岭石的生成。当煅烧温度约１１００℃时，生成相当数量的莫来石的同时存在较多的玻璃体，以致也具有良好的活性。
The fact that coal mine refuse of Yongcheng is sandy mudstone was confirmed by XRD.Although the main clay mineral is Kaolinite, the structural change during heating is different from pure kaolinite. When the temperature of calcination reaches to 900℃,the activity comes from the production of metakaolinite.When the temperature of calcination reaches to 1100℃,a lot of mullite as well as certain quantity of vitrified substance are prouduced and they have good activity.
