摘要
采用电化学除盐的方法对盐污染混凝土进行除盐试验,结果表明在除盐早期,混凝土中氯离子排除量主要与电流密度和混凝土中氯离子的含量直接相关,电化学除盐后混凝土内部的氯离子含量呈由里及外逐渐增大的趋势;而上下两端面的氯离子含量较少,中间段的较高。
Concrete polluted by chloride ions was investigated with electrochemical chloride extraction （ECE） technology. The concentration of chloride ions extracted from concrete was connected directly to the current density and initial chloride ion content in the desalination early age. Chloride ions distribution in concrete increased gradually from inner sample to peripheral sample after desalination and chloride ion content was less in the top and underside than in the middle of the concrete.
