给出了二元磨细高炉渣水泥体系的反应模型和水化产物体积分数的定量计算，其中考虑了矿渣二元磨细粉的化学组成对其反应活性的影响和水化硅酸钙(C-S-H)凝胶中铝相的部分置换。在此基础上，进一步提出了量化处理的简化方法。特别是，当GGBFS的取代量低于70%时，钙与二氧化硅的比例(C/S)设置为1.5，否则设置为1.2。根据钙质波特兰石和非蒸发水的含量对模型的有效性进行了讨论。
The reaction models and the quantitative calculation on the volume fraction of hydration products for binary ground granulated blast-furnace slag (GGBFS) cement system are presented, in which two important factors are taken into account,i e, the reactivity of GGBFS influenced by its chemical compositions and the partial replacement of aluminum phase in calcium silicate hydrate (C-S-H) gel. A simplified treatment is further suggested towards the quantification. In particular, when the replacement level of GGBFS is lower than 70%, the ratio of calcium over silica (C/S) is set at 1.5 or at 1.2 otherwise. The validity of the proposed model is addressed in terms of the contents of calcium Portlandite and non-evaporable water.
