摘要
通过热失重(TGA)、XRD和综合热分析(TSC-TG)测试,研究了低钙粉煤灰在不同外加剂和温度作用下的活化机制。特别是对粉煤灰中莫来石结构稳定性进行了探讨,结果显示,即使在强碱作用下,莫来石受侵蚀程度仍然很小。因此在研究粉煤灰活性时,可以不考虑莫来石的影响。
Activation of low calcium fly ash, in different admixtures and at different temperatures, was stu- died by TGA, XRD and TSC-TG analysis. Especially, the stability of mullite structure of fly ash was studied. Results show that even in alkali surrounding, erosion of mullite by alkali is weak. So in studies of the activity of fly ash influ- ence of mullite can be ignored.
