活化煤矸石在水泥砂浆中的应用研究

Research on Application of Activated Coal Gangue in Cement Mortar

同时采用煅烧、机械细磨和添加化学激发剂三种手段加工处理煤矸石,采用力学性能测试研究了水泥砂浆的强度,通过XRD分析了煤矸石的成分和结构。试验结果表明,经复合加工处理后,煤矸石活化效果明显,得到的活化煤矸石掺混水泥胶砂强度较高。水玻璃的加入可进一步提高煤矸石的活性。经700℃煅烧,水玻璃加入量为1%样品的砂浆强度最高。

In this thesis, the calcination, mechanically fine grinding and adding chemical activator were used at the same time to process coal gangue, mechanical property testing was taken to research the strength of cement mortar, and XRD （X-ray diffraction） was adopted to analyze the composition and structure of coal gangue. The results showed that through the complex processing, the activation effect of coal gang^ae is significant, and the strength of cement mortar mixed with activated coal gangue is high, the activity of coal gangue processed with water glass is further improved, and the highest strength cement mortar group is the one mixed with coal gangue that was burned at 700℃ and compounds from 1% water glass.
