摘　　要：与硅酸三钙相比,硫铝酸钙、硅酸二钙和硫硅酸钙等具有钙含量低、烧成温度低和CO_(2)排放量少的特点,属于低钙水泥熟料矿物。发展以低钙矿物为主要组成的水泥熟料是水泥低碳发展的重要方向。本文在分析硫铝酸钙、硅酸二钙和硫硅酸钙3种低钙矿物的活性、水化和性能发展的基础上,分别对以低钙矿物为主要矿物的硫铝酸盐水泥熟料、高贝利特硫铝酸盐水泥熟料的水化和性能发展,硅酸二钙–硫铝酸钙–硫硅酸钙水泥熟料的制备、水化和性能优化进行了综合评述。同时,鉴于石膏在低钙水泥熟料水化方面具有重要影响,综述了石膏在几种低钙水泥中的作用。文章以期为运用硫铝酸钙、硅酸二钙和硫硅酸钙等矿物制备低钙水泥熟料提供参考。Low-calcium clinker minerals(i.e.,ye'elimite,belite and ternesite)have lower calcium content,reduced firing temperature,and decreased CO_(2)emission,compared to alite.The development of clinkers primarily composed of these low-calcium minerals represents a significant direction for the sustainable,low-carbon evolution of cementitious materials.This review represented the hydration and performance development of ye'elimite,belite and ternesite,the hydration and performance development of calcium sulfoaluminate cement and belite-ye'elimite-ferrite cement,as well as the preparation,hydration and performance optimization of belite-ye'elimite-ternesite,respectively,with both low-calcium minerals as major minerals.Meanwhile,the effect of gypsum on the low-calcium cement was discussed due to its crucial influence in the hydration of cement clinker.This review could provide a reference for the synthesis of low-calcium clinkers primarily using ye'elimite,belite and ternesite.
