摘要
通过热失重(TGA)、XRD、孔结构和综合热分析(TSC-TG)的测试,研究了粉煤灰在不同外加剂和加热作用下的活化机制。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。
Activating of fly ash, in the different admixtures and temperatures, had been studied by the methods of TGA, XRD, pore structure and TSC-TG analysis. Especially, the stability of Mullite structure of fly ash was studied. Results show that erosion of alkali on the Mullite is weak although in the alkali surrounding, so when activation of fly ash was studied, the influence of Mullite can be ignored.
