摘要：用結(jié)合水量、三甲基硅烷化―氣相色譜、差熱分析和X射線衍射等方法研究了激發(fā)劑對(duì)粉煤灰水泥膠凝材料水化性能的影響，發(fā)現(xiàn)激發(fā)劑能加快粉煤灰水泥膠凝材料的水化速度，使粉煤灰先解聚再水化.粉煤灰中單摻激發(fā)劑，水化反映難以進(jìn)行.激發(fā)劑對(duì)粉煤灰水泥膠凝材料的水化產(chǎn)物種類影響不大.

Abstract：The effects of activator on the hydration properties of fly ash-cement binders are studied by use of bound water, TMS-GC, DTA and XRD. It is found that the hydration of fly ash-cement binders is accelerated by activator and fly ash is depolymerized prior to hydration. The hydration of fly ash is difficult by adding activator alone. The activator has little effect on the kinds of hydration products.
Key words：fly ash;cement;activator;hydration properties
