摘　　要：对混凝土抗硫酸盐腐蚀性的评价指标进行优化设计,设计出评价参数后,采用评价参数来表征绿色高性能混凝土(GHPC)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系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;采用设计的评价参数对GHPC的抗硫酸盐腐蚀性进行评价,能更好地判断混凝土所处的性能状态.The assessment indices of performance of anti-sulfate erosion were optimized for the concrete and the assessment parameters were designed.The process of performance deterioration of green high-performance concrete was characterized by using designed assessment parameters.The result showed that deterioration degree of every performance of the concrete could be shown on the same coordinate system with the assessment parameters.The assessment parameters were suitable to applicable the same discrimination criterion, the discrimination principle was simple and convenient, and it was easy to be used for comparing the deterioration course and sensitivity degree of every performances of the concrete. The concrete performance state could be well assessed with the designed assessment parameters when the GHPC performance of anti-sulfate erosion ability was assessed.
