摘　　要：为探讨高抗硫水泥混凝土在硫酸盐、镁盐双重侵蚀环境下的抗侵蚀性能,对不同水灰比的高抗硫水泥胶砂试件,进行不同浓度的硫酸盐、镁盐双重侵蚀试验,试验结果表明:高抗硫水泥混凝土只能抵抗低浓度(SO_4^(2-)≤2 500 mg/L,Mg^(2+)≤600 mg/L)硫酸盐、镁盐的双重侵蚀,难以抵抗较高浓度硫酸盐、镁盐的双重侵蚀;在低浓度双重侵蚀环境中,降低水灰比有利于增强高抗硫酸盐水泥混凝土的抗蚀能力。To explore high sulfate- resistant cement concrete in sulfate,magnesium salt erosion resistance under double erosion environment,with different water/cement ratio of high sulfur cement mortar specimens,for different concentrations of double sulfate,magnesium salt erosion test,test results show that the high sulfur cement concrete can resist low concentration（SO_4^（2-）≤2 500 mg/L,Mg^（2＋）≤600 mg/L） or less the double erosion of sulfate,magnesium salt,it is difficult to resist the high concentration of sulfate,magnesium salt erosion; In the low concentration of double erosion environment,reduce water-binder ratio is beneficial to enhance high sulfate corrosion resistance of the cement concrete.
