中文摘要：

沿海、盐碱地电厂等混凝土建、构筑物受盐害作用，导致其使用寿命降低。故引入对三乙烯四胺双向电渗短期效果的研究。对混凝土试块进行恒流通电，采用不同通电时间以及通电电流密度，研究三乙烯四胺阻锈剂在混凝土试块中的双向电渗效果。结果表明：混凝土试块中氯离子排出量随通电时间和通电电流密度成递增关系；三乙烯四胺阻锈剂迁入量和通电时间成递增关系，和通电电流密度没有明显关系。同时，通电后测量，钢筋的腐蚀电势以及钢筋／溶液界面电荷转移电阻均有不同程度增大，但其腐蚀电流也有一定程度增大。试验结果表明三乙烯四胺阻锈剂具有良好的双向电渗效果，双向电渗效果在t=15d，D=3A／m2达到最佳。

英文摘要：

In coastal and saline alkali area,power plants and other concrete structures are subjected to salinization,resulting in decrease of service life.Therefore, it introduced a short-term experimental study of electrical parameters for bilateral electro-osmotic method with triethylenetetramine inhibitor.The concrete block is tested with galvanostatic method,with different electrical time and electrical current density, it studied the bilateral electro-osmotic effect of triethylenetetramine （TETA） inhibitor in the concrete block.The results show that the discharge capacity of chloride ion in concrete block increased with the electrical time and electrical current density.And the immigration amount of TETA inhibitor increased with the electrical time, which shows no obvious relationship with the electrical current density.At the same time, the corrosion potential of the steel and the charge transfer resistance of the steel/solution interface increased after the electric power, but the corrosion current increased to some extent.The results show that TETA inhibitor has good bilateral electro-osmotic effect.In this experiment, the bilateral electro-osmotic effect reached the best testing at the parameter： t=l 5 d, D=3 A/m2.
