摘　　要：对水泥 -磨细矿渣胶凝体系水化产物—F盐的微观结构试验表明 ,F盐的X射线衍射强度峰出现在最大晶面距d =80nm附近 ,吸热峰出现在 36 0℃左右 ,其六方片状晶体的尺寸约为 2～ 3μm .此外 ,分析了影响F盐生成的因素 ,籍此解释了大掺量磨细矿渣胶凝体系具有优越的氯离子结合性能的原因 .The microstructure of Friedel's (F) salt in hydrate of cement and granulated ground blast furnace slag (GGBS) is experimentally studied. It can be seen that the maximum XRD intensity of F salt appears at 80 nm and that an endothermic effect yields at around 360℃. The morphology of F salt is a hexagonal slice with a size of 2～3 micrometers. The influence of F salt's formation is analyzed, and the mechanism of chloride binding capability of cement with great volumes of GGBS is also explained.
