| 水泥 矿渣二元体系水化产物体积分数的定量计算是理论预测其微结构发展的重要基础。根据水泥 矿渣水化反应特征，文中给出了详细的计算表达式；采用热重 差示扫描量热(TG DSC)综合分析手段来验证所提表达式的合理性，并根据Jennigs Tennis模型(简称J T模型)，给出了低密度和高密度C S H凝胶体积分数的定量计算公式，对水泥 矿渣二元体系中两种凝胶的相对量进行定量计算。结果表明：水泥 矿渣二元体系中矿渣完全水化的最佳掺量为54.4%，两种凝胶的相对量随矿渣掺量的增加而增加。 |

| Quantitative calculation of volume fraction of hydration products of cement slag binary system is the important theoretical foundation for predicting its microstructure development. According to the cement slag hydration characteristics, detailed calculation expressions are given in this paper, and then thermogravimetry differential thermogravimetry (TG DTG) is applied to validate the expressions mentioned above. Furthermore, based on the Jennigs Tennis model, volume fraction of the low density and high density C S H in cement slag are calculated. The results show that the best dosage of slag is 54.4% in cement slag binary systems and the relative amount of two types of C S H increases with the increase in slag. |
