摘要:

无水硫铝酸钙(C4A3S)是硫铝酸盐水泥的主要熟料矿物,具有碳排放低和早期活性高等特点。C4A3S存在立方、正交和四方三种晶型,不同晶型在水化活性方面表现出显著差异。因此,阐明C4A3S晶体结构与水化活性之间的关系,并实现其晶型的有效调控,对于开发新型硫铝酸盐水泥熟料体系具有重要意义。本文系统综述了C4A3S的晶型调控方法,包括温度调控法、熔盐法和离子掺杂法,重点分析了不同调控方法的作用效果及机理。在此基础上,结合不同晶型C4A3S的结构特征,总结分析了晶型调控对其水化动力学、水化活性及水化产物的影响规律,为C4A3S晶型调控技术在硫铝酸盐水泥中的应用提供参考。

Abstract:

Ye’elimite (C4A3S) is the principal clinker mineral in sulfoaluminate cement, characterized by low carbon emissions and high early-age reactivity. C4A3S exists in three polymorphic forms: cubic, orthorhombic, and tetragonal systems, which exhibit distinct hydration activities. Therefore, elucidating the relationship between crystal structure and hydration activity of C4A3S and achieving effective regulation of its crystal form are of great significance for developing novel sulfoaluminate cement clinker systems. This paper systematically reviews the crystal form regulation methods of C4A3S, including temperature control method, molten salt synthesis method, and ion doping method, with emphasis on analyzing the efficacy and underlying mechanisms of different regulation methods. On this basis, combined with the structural characteristics of various C4A3S crystal form, the influence of crystal form regulation on hydration kinetics, hydration activity, and hydration products is summarized and analyzed, providing theoretical references for the application of C4A3S crystal form regulation technology in sulfoaluminate cement.
