烟气脱硫石膏及其建材资源化研究

摘要

This paper introduces the investigation results on FGD gypsum and its utilization in building materials. Tests are made to materials with PGD includes plaster of paris ,plaster of gypsum,gypsum block (panel),plaster board, gypsum putty, cement retarder and dihydrate gypsum binder. The results indicate that FGD gypsum is a valuable resource of the industry of building materials because of its high quantity of CaSO4 · 2H2O and convenience in use,and the research and development on FGD gypsum should be further strengthened.%介绍了作者在烟气脱硫石膏及其作为主要原料制备建筑石膏、粉刷石膏、石膏砌块(条板)、纸面石膏板、腻子、水泥缓凝剂、二水石膏胶结材等建材资源化方面的研究结果。结果表明，烟气脱硫石膏的品位较高，便于利用，是建材工业的宝贵资源，应进一步加大研究开发力度。
