为了方便研究混凝土受硫酸盐侵蚀的影响因素及劣化过程中混凝土各项性能的变化和敏感程度,本文设计了一种综合评价参数对混凝土抗硫酸盐性能进行评价。结果表明:综合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;综合评价参数判定法则简单、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。同时,试验过程得出:采用文中设计的评价参数对不同配合比及掺合料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。
In order to facilitate the study of concrete affected by sulfate erosion factors and deterioration of concrete during the performance of the changes and sensitivity, this paper designed a comprehensive evaluation of the parameters of concrete sulfate resistance evaluation. The results show that the comprehensive evaluation parameters can show the deterioration degree of various properties of concrete on the same axis. The judgment rules of comprehensive evaluation parameters are simple and convenient, and it is easier to compare the process and sensitivity of various properties in the process of concrete deterioration. At the same time, the test results show that the evaluation parameters of the design parameters in the paper are used to evaluate the sulfate resistance of different mixes and admixture concrete, which can better judge the performance state of concrete.
