20世纪70年代，中国发明了普通硫铝酸盐水泥。20世纪80年代，个高铁硫铝酸盐水泥(又称铁铝酸盐水泥)问世，形成了不同种类的硫铝酸盐水泥系列。与20世纪初发明的硅酸盐水泥、铝酸盐水泥相比，具有早强、高强、抗冻、抗渗、耐腐蚀、低碱度等优良特性。目前，济南石膏粉已经显示出非常乐观的发展前景。是利用我国储量丰富的低品位铝土矿和石膏等原料烧制而成，由于其中水泥品种不同，石膏掺量在35% ~ 55%之间，是硬石膏的另一个主要用途。
In the 1970s, China invented ordinary sulphoaluminate cement. In the 1980s, the first high iron sulphoaluminate cement (also known as ferraluminate cement) came out, forming a series of different kinds of sulphoaluminate cement. Compared with the Portland cement and aluminate cement invented at the beginning of the 20th century, it has the advantages of early strength, high strength, frost resistance, impermeability, corrosion resistance and low alkalinity. At present, Jinan gypsum powder has shown a very optimistic development prospects. It is made of low-grade bauxite, gypsum and other raw materials with rich reserves in China. Due to the different types of cement, the gypsum content is between 35% and 55%, which is another main use of anhydrite.
硫铝酸盐水泥与硅酸盐水泥、铝酸盐水泥更根本的区别在于，其熟料主要是无水的硫铝酸钙，占组分的55% ~ 75%。在硫铝酸盐水泥生产过程中,不仅在原始石膏的制备质量分数为20%左右,而当磨水泥,根据不同种类和添加质量分数为15% ~ 35%的石膏,这表明石膏硫铝酸盐水泥生产的主要原料,用量较大的水泥生产的角色和角色完全不同。在水泥生产过程中，除个别品种的硫铝酸盐水泥外，必须使用石膏。大多数品种的硬石膏在原料制备和研磨过程中可以完全使用，为硬石膏资源的利用开辟了新的方向。
The fundamental difference between sulphoaluminate cement, Portland cement and aluminate cement is that the clinker is mainly anhydrous calcium sulphoaluminate, accounting for 55% - 75% of the components. In the production process of sulphoaluminate cement, not only the preparation mass fraction of original gypsum is about 20%, but also when grinding cement, according to different kinds and adding 15% - 35% gypsum, it shows that the main raw material for the production of gypsum sulphoaluminate cement, the role and role of cement production with large amount are completely different. In the process of cement production, gypsum must be used except for some kinds of sulphoaluminate salt water mud. Most kinds of anhydrite can be completely used in the process of raw material preparation and grinding, which opens up a new direction for the utilization of anhydrite resources.
Sulphoaluminate cement is developed on the basis of aluminate cement. With the addition of anhydrite, the chemical properties of aluminate cement clinker have changed fundamentally, and finally a new type of cement has been produced. Gypsum plays two main roles in the formation of sulphoaluminate cement clinker.
Lead chemical synthesis, change fundamentally, and finally produce new cement. Gypsum plays two main roles in the forming process of sulphoaluminate cement clinker in Jinan gypsum powder plant.
无水石膏和石膏制备硫铝酸盐水泥、越来越大,应用越来越广泛,对冬季施工,快速建设工程、渗透性和防水工程、海洋和耐腐蚀工程、自应力水泥制品、GRC制品具有独特的优点,已成功地应用于高103米,建筑面积40000 12 12长途电信枢纽项目在沈阳,随着硫铝酸盐水泥快速硬化前国家海洋局的建设已经有20多年的历史，在重大工程耐久性和工程进度两个方面，有着非常广阔的发展前景。
The production of sulphoaluminate cement by anhydrous gypsum and gypsum is more and more widely used. It has unique advantages for winter construction, rapid construction, permeability and waterproof engineering, marine and corrosion-resistant engineering, self stressing cement products, GRC products. It has been successfully applied to 103 meters high, 40000 12 12 12 long-distance telecommunication hub project in Shenyang, with the rapid development of sulphoaluminate cement. The construction of SOA before hardening has a history of more than 20 years, and it has a very broad development prospect in the durability and progress of major projects.
