本文介绍了硫铝酸盐系列水泥的基本概念和基本分类;回顾了硫铝酸盐水泥的发展历程及相关国家标准的变迁;分析了硫铝酸盐水泥的矿物组成以及硫铝酸盐水泥的物理化学性质。硫铝酸盐水泥具有优异的环境耐受性,可以有效抵抗复杂环境的侵蚀破坏。通过调整外掺材料的组成,可以实现生产不同功能的特种工程材料。分析表明硫铝酸盐水泥作为水泥行业的高端细分产业,有较高的技术门槛和市场门槛,同时也存在巨大利润空间。从长远来看,为了提升工程质量,增强筑件性能,尤其是破损建筑物的修补加固,因地制宜的使用硫铝酸盐系列水泥是工程建设的必然趋势。同时指出相对于硅酸盐系列水泥来说,对硫铝酸盐系列水泥的研究应用,远远不够。因为缺乏相应的设计和施工规范,缺乏相应细致详实的理论指导,导致在部分应该使用硫铝酸盐水泥的地方没有使用。
This paper introduces the basic concepts and basic classification of sulphoaluminate cement; reviews the history of sulphoaluminate cement and the changes of related national standards; analyzes the mineral composition of sulphoaluminate cement and the influence of sulphoaluminate cement Physicochemical properties. Sulphoaluminate cement has excellent environmental resistance and can effectively resist the erosion and destruction of complex environment. By adjusting the composition of the external material, special engineering materials with different functions can be realized. Analysis shows that sulphoaluminate cement as a high-end segment of the cement industry industry, a higher technical threshold and market threshold, but also there is a huge profit margin. In the long run, in order to improve the quality of construction and enhance the performance of building materials, especially repair and reinforcement of damaged buildings, it is an inevitable trend to use sulphoaluminate cement according to local conditions. At the same time, it is pointed out that the application of sulphoaluminate cement is far from enough compared with silicate cement. The lack of correspondingly detailed and detailed theoretical guidance due to the lack of corresponding design and construction practices led to the unavailability of parts where sulphoaluminate cement should be used.
