摘要/Abstract

摘要： 为探究氯盐和杂散电流耦合作用下混凝土阻抗性能的变化规律,通过实验室模拟方法研究地铁用混凝土在氯盐和杂散电流双重侵蚀下的性能变化。结果表明,随着侵蚀龄期增加,混凝土的电阻率逐渐降低;氯盐和杂散电流耦合侵蚀显著降低混凝土的高频弧直径;侵蚀作用下混凝土的非连通导电路径电阻呈先增加后降低的趋势,电容呈先降低后增长的趋势。可见,氯盐和杂散电流耦合作用会减少有害离子在混凝土中传输阻碍,加快钢筋锈蚀进而降低混凝土耐久性。本研究可以为地铁混凝土结构的耐久性评估和防护提供科学依据。

Abstract: In order to investigate the variation law of impedance performance of concrete under the coupling effect of chloride salts and stray currents, the performance change of concrete for underground under the double erosion of chloride salts and stray currents was investigated by laboratory simulation method. The results show that the resistivity of concrete gradually decreases with the increase of erosion age. Chloride salts and stray currents coupled erosion significantly reduce the high frequency arc diameter of concrete. And the resistance of the unconnected conducting path of concrete under erosion tended to increase and then decrease, while the capacitance tended to decrease and then increase. The coupling effect of chloride salts and stray currents reduces the obstruction to harmful ion transport in concrete, accelerates steel corrosion, and thereby decreases concrete durability. This study can provide a scientific basis for the durability assessment and protection of metro concrete structures.

Key words: chloride salt erosion, stray current, concrete impedance, durability, electrochemical test
