| 摘 要： | 对江苏宜兴煤矸石的基本物性分析知,其主要矿物成分为高岭石和石英,化学成分中Cao的含量相对较低.于煤矸石高温煅烧过程中引入不同掺量的CaO后制成活化煤矸石样,采用X射线衍射分析法(XRD)对其活化过程的结构特征进行分析,同时采用比强度法对部分活化煤矸石的火山灰效应进行评定.结果表明:煅烧温度较低时,生成的硅酸盐矿物较少...

| Abstract: | tudied on coal gangue from Jiangsu Yixing,its mineral composition was Kaolinite and Quartz and in chemical composition the content of CaO was relatively low.Activated coal gangue samples made by different amount of CaO were introduced during the calcination process of coal gangue.Structure characteristic of the samples were examined by X-ray diffraction analysis.By specific strength concept,the pozzolanic effect of activated coal gangue could be investigated.Results show that,when calcination temperature wa... |
