The paper studies the impact of sulfate erosion damage upon engineering structure safety of structural concrete. Through experimental research,it explores anti-sulfate erosion conditions with single-concrete mixing and anti-sulfate performance with double-mixing high-performance concrete,and points out that mineral mixing amount and water-fly ash ratio are critical factors deciding concrete sulfate resisting performance.%针对结构混凝土因硫酸盐侵蚀破坏影响工程结构安全的问题作了研究，通过试验探讨了单掺粉煤灰时混凝土抗硫酸盐侵蚀情况及双掺合料高性能混凝土的抗硫酸盐性能，指出矿物掺合料的掺加量和水灰比是决定混凝土抗硫酸盐性能的关键因素。
