对六盘水矿区煤矸石原粉组成进行分析,测定了煤矸石原粉和活化煤矸石粉制备免烧砖的胶凝性能,系统地研究了机械、热、化学及复合活化方式对原状煤矸石活性激发作用。研究表明,六盘水矿区煤矸石属于高铁高砂型煤矸石,活化煤矸石能够显著提高煤矸石基免烧砖的胶凝性能,复合活化效果优于单一活化方式,复合活化的煤矸石能够大幅度地提高免烧砖的胶凝性能,达到JC/T422-91(96)《非烧结普通黏土砖》MU15的标准。

The composition of coal gangue powder in Liupanshui mining area was analyzed and the strengths property of original and activated coal gangue based unfired brick were determined. The effects of mechanical, thermal, chemical and compound activation on the coal gangue were systematically studied. The results showed that coal gangue has the characteristics of high silicon content, high iron content in Liupanshui mining area. Activated coal gangue can improve considerably the strengths property unfired brick. The compound activation method is superior to the single activation method. Compound activated coal gangue can enhanced sharply the strengths property of unfired brick , then unfired brick fully meets the standard of JC/T422-91 (96) MU15.
