| 摘要: |
| 对水泥－靡细矿渣胶凝体系水化产物－F盐的微观结构试验表晨，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360℃左 右，其六方片状晶体的尺寸约为2－3um。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 氯离子经生能的原因。 |

| Abstract: |
| The microstructure of Friedel's (F) salt in hydrate of cement andgranulated 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. |
