摘　　要：对混凝土抗硫酸盐腐蚀性的评价指标进行合理的优化设计后,采用设计后的评价参数来表征混凝土在硫酸盐环境中的性能劣化过程。结果表明:评价参数能在同一坐标轴上显示混凝土各项性能的劣化程度;评价参数适用相同判定标准,判定法则简单、方便,更易于比较混凝土劣化过程中各项性能的变化过程和敏感程度;采用文中设计的评价参数对粉煤灰混凝土的抗硫酸盐腐蚀性进行评价,能更好的判断混凝土所处的性能状态。After the assessment indexes on concrete performance of anti-sulfate erosion are optimized rationally, the course on performance deterioration of concrete is characterized by assessment parameters. The results show that each performance deterioration degree of concrete can be compared on the same coordinate axis by the assessment parameters. The assessment parameters are applicable to the same estimation criterion, and the estimation principle is simple and convenient. The comparison of the deterioration course on concrete performance is much easy. It is better to estimate concrete performance by the way the performance of anti-sulfate erosion for the concrete containing fly ash is assessed by the assessment parameters.
