| 摘 要： | 主要研究在水玻璃激发条件下,矿渣、粉煤灰、水泥按一定的配合比配制成复合胶凝材料,并对这种复合胶凝材料的抗硫酸盐侵蚀性能进行研究。试验采用正交实验法,以获得高抗硫酸盐侵蚀能力的复合胶凝材料的最优配比;并采用XRD、SEM和MIP等手段对其机理进行了研究探讨。结果表明:(1)掺加矿物掺和料的水泥比普通硅酸盐具有更好的抗硫酸盐侵蚀性能;(2)试验条件下的高抗硫酸盐侵蚀能力的复合胶凝材料的最佳配比为:矿物掺合料与水泥的掺量比为7:3,矿物掺合料中矿渣与粉煤灰掺量比为4:6,水玻璃掺量与矿物掺合料总量比为7%。

| Abstract: | Slag, fly ash and cement were mixed at a proportion under the excitation of water glass, and a compound cementitious material was produced, and its sulfate resistance was studied. Orthogonal test was took to get the best proportion, and by XRD and SEM the mechanism was studied. The results indicated that the corrosion resistance of the compound cementitious material was better than that of the portland cement, and the best proportion of compound high-sulfate-resistance cementing material was mineral mixture/cement= 7：3, slag/fly ash= 4：6, and water glass/mineral mixture=7%. |
