摘　　要：利用脱硫石膏生产建筑石膏已经成为当前解决固体排放物问题的有效途径。粉刷石膏在耐水性和力学性能等方面的弱点影响其使用范围。本文研究复合掺加不同含量的活性掺合料对石膏制品耐水性和力学性能的影响。研究表明,掺加水泥和矿渣的效果最好,其耐水性可以提高40%,力学性能提高48%。The use of FGD gypsum for construction gypsum production has become a valid way to solve solid waste. The weakness of water resistance and mechanical properties impacted the scope of plastering gypsum application. In this study, the improvement of water resistance and mechanical property was achieved by adding different activity admixtures on FGD plastering gypsum. The results indicate that product mixing cement and slag has best performance, which improve water resistance by 40% and mechanical property by 48%.
