關于石膏粉天然硬石膏的發展

　　石膏粉:天然硬石膏的發展在20世紀70 ~ 80年代,邵盾,南京等地的大型硬石膏礦山建立和實現一個接一個的“改革開放”,各種工廠和礦山,科研機構和高等院校的理論和應用研究天然硬石膏推向高潮,這不僅可以找到硬石膏水泥凝固,并且可以增強,還能提高水泥漿體的流動性和硬化體的密實度，在制備硬化快的硫鋁酸鹽水泥、礦渣水泥、油井水泥、低堿水泥和各種硅酸鹽水泥方面取得了良好的效果。

　　Gypsum powder: the development of natural anhydrite in the 1970s-1980s, shaodun, Nanjing and other large anhydrite mines established and realized one after another "reform and opening up", various factories and mines, scientific research institutions and colleges and universities of theory and Application Research of natural anhydrite pushed to a climax, which can not only find the setting of anhydrite cement, but also enhance, It can also improve the fluidity of cement paste and the density of hardened body, and has achieved good results in the preparation of sulphoaluminate cement, slag cement, oil well cement, low alkali cement and various Portland cement with fast hardening.

　　1985年，國家正式頒布了《水泥用石膏和硬石膏標準》(GB 5483 85)，硬石膏的應用進入了一個新階段。同時對硬石膏的水化硬化、活化機理以及硬石膏水泥的生產和應用進行了研究。20世紀90年代以來，硬石膏的活化技術有了新的進展，硬石膏的水化硬化速度、耐水性和強度都有了很大的提高。現在除了使用硬石膏作為水泥混凝劑和生產各種水泥外，硬石膏還用于生產膨脹劑、地坪抹灰、石膏抹灰、模型抹灰、人造大理石、硬石膏砌塊、硬石膏陶瓷和各種板材等建筑材料。由于我國硬石膏儲量豐富，具有加工工藝簡單、節約能源、也具有利用廢渣、保護環境等優點，在未來必將得到迅速的發展。

　　In 1985, the state officially promulgated the standard of gypsum and anhydrite for cement (GB 548385). The application of anhydrite has entered a new stage. At the same time, the hydration hardening and activation mechanism of anhydrite and the production and application of anhydrite cement were studied. Since the 1990s, the activation technology of anhydrite has made new progress, and the hydration hardening speed, water resistance and strength of anhydrite have been greatly improved. Now in addition to using anhydrite as cement coagulant and producing various cements, anhydrite is also used to produce building materials such as expansion agent, floor plastering, gypsum plastering, model plastering, artificial marble, anhydrite block, anhydrite ceramics and various boards. Due to the abundant reserves of anhydrite in our country, it has the advantages of simple processing technology, energy saving, waste residue utilization and environmental protection, and it will be developed rapidly in the future.
