摘要 在激发剂的作用下,利用矿渣改性磷石膏(PG)制备磷石膏基胶凝材料(PGS),然后研究掺入钢渣和粉煤灰制备磷石膏复合材料的性能情况。结果表明:当激发剂掺量在3%时,在20℃(湿度大于70%)养护下PGS固化体28d的抗压强度和抗折强度(41.9MPa和7.1MPa)分别较未掺激发剂的提高了47.3%和42.3%,28d软化系数为0.94;当钢渣比例在1:1时,磷石膏砂浆性能最佳,28d抗压强度和抗折强度分别为57.1MPa和4.8MPa;粉煤灰掺量在20%时,磷石膏砂浆抗压强度和抗折强度分别为22.1MPa和3.4MPa,吸水率和软化系数分别为4.9%和0.94,质量损失率、抗压强度损失率和抗折强度损失率分别为1.5%、4.5%和4.3%。 The paper studies the performance of phosphorus gypsum composites, which consists of the steel slag, fly ash and the phosphorus gypsum cementitious materials (PGS) prepared by slag modified phosphogypsum (PG) and activator.
