| 摘 要： | 硫铝酸盐水泥具有煅烧温度低、CO2排放少、快硬早强以及抗冻抗渗等优良特性,在建材、固废领域具有广阔的应用前景,并衍生出贝利特-硫铝酸钙、贝利特-硫铝酸钡钙等一系列硫铝酸盐水泥。然而,硫铝酸盐水泥主要矿物成分贝利特(β-C2S)具有水化活性低、水化速度慢的缺点,易导致水泥后期强度增长缓慢。硫硅酸钙(C5S2$\bar{\text{S}}$)曾被认为是一种“惰性”矿物,但在硫铝酸盐体系下可表现出比β-C2S更强的水化活性,因此硫硅酸钙-硫铝酸盐水泥(TSAC)的研究具有重要意义。本文从C5S2$\bar{\text{S}}$矿物的形成和水化、TSAC的制备和性能等方面,综述了C5S2$\bar{\text{S}}$和TSAC的研究现状,并提出了TSAC需进一步研究和解决的问题,如固废原料探寻、TSAC性能调控以及TSAC熟料矿物组成优化等,以期为新型低碳水泥的研究和应用提供积极有利的参考和支持。

| Abstract: | Sulphoaluminate cement has excellent performances, such as low sintering temperature, low CO2 emission, fast hardening and early strength, frost resistance and impermeability. It has broad application prospects in the field of building materials and solid waste, and derived a series of sulphoaluminate cements such as belite-calcium sulphoaluminate cement and belite-barium calcium sulphoaluminate cement, and etc. However, belite (β-C2S), one of the main mineral components of above sulphoaluminate cement, has low hydration activity and slow hydration speed, easily resulting in slow growth of cement strength in the later stage. Ternesite (C5S2$\bar{\text{S}}$) was once considered to be an “inert” mineral, but it can show stronger hydration activity than β-C2S in sulphoaluminate system, so the research on ternesite-sulphoaluminate cement (TSAC) is of great significance. Firstly, this paper summarizes the research status of C5S2$\bar{\text{S}}$ and TSAC from aspects such as the formation and hydration of C5S2$\bar{\text{S}}$, and the preparation and performance of TSAC. Secondly, this paper puts forward the problems that TSAC needs to further study and solve, such as the exploration of solid waste materials, the performance regulation of TSAC and the optimization of mineral composition of TSAC clinker. Overall, it is expected to provide positive and favorable reference and support for the research and application of new low-carbon cement. |
