摘　　要：本文以脱硫建筑石膏和掺和料为主要原料,配制了粘结石膏,结合宏观性能试验和微观分析,探究了掺和料的作用机理,优化了粘结石膏的配合比。试验发现,内掺20%水泥和20%粉煤灰能够有效降低需水量,改善料浆流动性,提高硬化体内部密实度和强度,改善硬化体耐水性。In this paper, gypsum binder was made from cal-cined gypsum from flue gas desulfurization and admixtures. The mechanism of interaction was explored, and the optimum mix was obtained by performance test and micro analysis. The experiment shows that the 20% cement and 20% fly ash can significantly re-duce water demand, and fluidity of slurry is improved, and also the density, strength and the resistance to water of the hardening of gypsum binder.
