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.

　　硫鋁酸鹽水泥與硅酸鹽水泥、鋁酸鹽水泥更根本的區(qū)別在于，其熟料主要是無水的硫鋁酸鈣，占組分的55% ~ 75%。在硫鋁酸鹽水泥生產(chǎn)過程中,不僅在原始石膏的制備質(zhì)量分?jǐn)?shù)為20%左右,而當(dāng)磨水泥,根據(jù)不同種類和添加質(zhì)量分?jǐn)?shù)為15% ~ 35%的石膏,這表明石膏硫鋁酸鹽水泥生產(chǎn)的主要原料,用量較大的水泥生產(chǎn)的角色和角色完全不同。在水泥生產(chǎn)過程中，除個(gè)別品種的硫鋁酸鹽水泥外，必須使用石膏。大多數(shù)品種的硬石膏在原料制備和研磨過程中可以完全使用，為硬石膏資源的利用開辟了新的方向。

　　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.

　　硫鋁酸鹽水泥是在鋁酸鹽水泥的基礎(chǔ)上發(fā)展起來的。硬石膏的加入使鋁酸鹽水泥熟料的化學(xué)性質(zhì)發(fā)生了根本性的變化，更終產(chǎn)生了一種新型的水泥。在硫鋁酸鹽水泥熟料的形成過程中，石膏起著以下兩個(gè)主要作用:

　　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.

　　引導(dǎo)化學(xué)合成，發(fā)生根本變化，更終生產(chǎn)出新型水泥。在濟(jì)南石膏粉廠硫鋁酸鹽水泥熟料的成型過程中，石膏起著兩個(gè)主要作用。

　　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.

　　無水石膏和石膏制備硫鋁酸鹽水泥、越來越大,應(yīng)用越來越廣泛,對冬季施工,快速建設(shè)工程、滲透性和防水工程、海洋和耐腐蝕工程、自應(yīng)力水泥制品、GRC制品具有獨(dú)特的優(yōu)點(diǎn),已成功地應(yīng)用于高103米,建筑面積40000 12 12長途電信樞紐項(xiàng)目在沈陽,隨著硫鋁酸鹽水泥快速硬化前國家海洋局的建設(shè)已經(jīng)有20多年的歷史，在重大工程耐久性和工程進(jìn)度兩個(gè)方面，有著非常廣闊的發(fā)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.
