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 optimization of the evaluation index of the sulfate resistance of the concrete, the post-design evaluation parameters are used to characterize the performance degradation of the concrete in the sulfate environment. The results show that the evaluation parameters can show the deterioration degree of various properties of concrete on the same axis; the same evaluation criterion applies to the evaluation parameters; the judgment rule is simple and convenient; and it is easier to compare the process and sensitivity of various properties in concrete deterioration process; Using the evaluation parameters designed in this paper, the evaluation of sulfate resistance of fly ash concrete can better judge the performance state of concrete.
