摘要
用结合水量、三甲基硅烷化—气相色谱、差热分析和X射线衍射等方法研究了激发剂对粉煤灰水泥胶凝材料水化性能的影响 ,发现激发剂能加快粉煤灰水泥胶凝材料的水化速度 ,使粉煤灰先解聚再水化 .粉煤灰中单掺激发剂 ,水化反映难以进行 .激发剂对粉煤灰水泥胶凝材料的水化产物种类影响不大 .
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.
