火山灰质材料火山灰活性检验方法的研究

摘要

利用火山灰性试验法、对比强度法、结合水率法以及TG-DTA同步热分析法对粉煤灰、煤矸石、偏高岭土和高岭土4种矿物原料进行了火山灰活性检测。结果表明，与常用的火山灰性实验法和对比强度法相比，结合水率法与TG-DTA同步热分析法具有实验周期短、量化更准确的特点。%The pozzolanic activity of lfy ash, coal gangue, kaolin and metakaolin were investigated by pozzolanicity test, pozzolanic activity index, hydration rate method and TG-DTA method. The results showed that: as compared with usual pozzolanicity test and pozzolanic activity index, hydration rate method and TG-DTA method has the advantages of rapidity and high accuracy.
