Abstract Thermodynamic modelling can reliably predict hydrated cement phase assemblages and chemical compositions, including their interactions with prevailing service environments, provided an accurate and complete thermodynamic database is used. Here, we summarise the Cemdata18 database, which has been developed specifically for hydrated Portland, calcium aluminate, calcium sulfoaluminate and blended cements, as well as for alkali-activated materials. It is available in GEMS and PHREEQC computer program formats, and includes thermodynamic properties determined from various experimental data published in recent years. Cemdata18 contains thermodynamic data for common cement hydrates such as C-S-H, AFm and AFt phases, hydrogarnet, hydrotalcite, zeolites, and M-S-H that are valid over temperatures ranging from 0 to at least 100 °C. Solid solution models for AFm, AFt, C-S-H, and M-S-H are also included in the Cemdata18 database.

Cemdata18：水合波特兰水泥和碱活化材料的化学热力学数据库

摘要 如果使用准确和完整的热力学数据库，热力学建模可以可靠地预测水化水泥相组合和化学成分，包括它们与主要服务环境的相互作用。在这里，我们总结了 Cemdata18 数据库，该数据库专为水合波特兰、铝酸钙、硫铝酸钙和混合水泥以及碱活化材料而开发。它以 GEMS 和 PHREEQC 计算机程序格式提供，包括根据近年来发表的各种实验数据确定的热力学特性。Cemdata18 包含常见水泥水合物的热力学数据，例如 CSH、AFm 和 AFt 相、水石榴石、水滑石、沸石和 MSH，这些数据在 0 到至少 100 °C 的温度范围内有效。
