A model for an ideal solid solution, developed by Nourtier-Mazauric et al. [Oil & Gas Sci. Tech. Rev. IFP, 60 [2] (2005) 401], is applied to calcium-silicate-hydrate (C-S-H). Fitting the model to solubility data reported in the literature for C-S-H yields reasonable values for the compositions of the end-members of the solid solution and for their equilibrium constants. This model will be useful in models of hydration kinetics of tricalcium silicate because it is easier to implement than other solid solution models, it clearly identifies the driving force for growth of the most favorable C-S-H composition, and it still allows the model to accurately capture variations in C-S-H composition as the aqueous solution changes significantly at early hydration times.
Nourtier-Mazauric等人[《石油与天然气科学技术评论》法国石油研究院，60 [2] (2005) 401]开发的一种理想固溶体模型被应用于硅酸钙水合物（C-S-H）。将该模型与文献中报道的C-S-H溶解度数据进行拟合，得出了固溶体端元组成及其平衡常数的合理值。该模型将有助于硅酸三钙水化动力学模型，因为它比其他固溶体模型更易于实施，能清晰地确定最有利的C-S-H组成的生长驱动力，并且在水化早期水溶液发生显著变化时，仍能使模型准确捕捉C-S-H组成的变化。
