| 摘 要： | 在矿物掺合料的掺量为30%情况下,分析粉煤灰、矿渣粉、水胶比对硫酸盐侵蚀性能的影响,结果表明:矿物掺合料能明显改善混凝土抗硫酸盐侵蚀的性能;对混凝土抗硫酸盐侵蚀性能改善效果方面,粉煤灰略优于矿渣粉;水胶比对混凝土抗硫酸盐侵蚀性的影响明显,水胶比越小,试件的抗压强度折损系数越高、质量损失率越小,混凝土的抗硫酸盐侵蚀性能越好;反之,水胶比越大,混凝土的抗硫酸盐侵蚀能力越差。

| Abstract: | Study on Resistance Sulfate Corrosion of High-performance Concrete under Dry-wet Cycle Test to understand the properties of Resistance Sulfate Corrosion. The effect of fly ash, slag powder and water - cement ratio on the corrosion resistance of High-performance concrete was analyzed under the condition that the content of mineral admixture was 30%. The analysis results show: mineral admixtures can significantly improve the properties of resistance sulfate corrosion on concrete, and the anti - erosion effect of fly ash is slightly better than slag powder. The properties of resistance sulfate corrosion are significantly affected by water-binder ratio. The smaller the water-binder ratio, the betterThe properties of resistance sulfate corrosio of high-performance concrete;The greater the water-binder ratio, the worse The properties of resistance sulfate corrosio of high-performance concrete. |

| Keywords: | high-performance concrete resistance sulfate corrosion coefficient of compressive strength damage loss rate of quality |
