中文摘要:
      热力学平衡计算近二十年在水泥化学领域得到了快速应用与发展，其计算结果能帮助研究人员更深入地认识水化反应的过程，极大地推动了水泥化学的进步以及胶凝材料体系的创新。对于任何一个化学反应体系，热力学平衡计算都是依据体系内所有固态、液态和气态反应成分的热力学性质（比如溶解度）来开展的。在诸多热力学模型之中，吉布斯自由能最小化（GEM）模型经常被用来计算平衡相的组分。由瑞士 PSI 开发和建立的 GEM-Selektor，全称为 Gibbs Energy Minimization Software for Geochemical Modeling作为水泥化学热力学模拟的主要工具之一，受到了广大水泥化学研究者的青睐。水泥热力学是理解水泥水化的重要内容。特别是对于研究一些新型水泥，在开展实验之前，利用热力学模拟对该体系进行初步了解和预判，可对实验设计起到至关重要的作用。本文利用GEMS模拟了硫硅酸钙对普通硅酸盐水泥水化性能的影响，对低碳水泥的研究开发提供了参考。
英文摘要:
      In the past two decades, thermodynamic equilibrium calculations have been rapidly applied and developed in the field of cement chemistry. The calculation results can help researchers gain a deeper understanding of the hydration reaction process, greatly promoting the progress of cement chemistry and the innovation of cementitious material systems. For any chemical reaction system, thermodynamic equilibrium calculations are carried out based on the thermodynamic properties (such as solubility) of all solid, liquid, and gaseous reaction components in the system. Among many thermodynamic models, the Gibbs Energy Minimization (GEM) model is often used to calculate the composition of equilibrium phases. GEM-Selektor, developed and established by PSI in Switzerland, with the full name of Gibbs Energy Minimization Software for Geochemical Modeling, is one of the main tools for thermodynamic simulation in cement chemistry and is favored by many cement chemistry researchers. Cement thermodynamics is an important aspect of understanding cement hydration. Especially when studying some new types of cement, using thermodynamic simulation to preliminarily understand and predict the system before conducting experiments can play a crucial role in experimental design. In this paper, GEMS was used to simulate the influence of calcium sulfosilicate on the hydration properties of ordinary Portland cement, providing a reference for the research and development of low-carbon cement.
