摘要 采用干湿循环渗透法,通过实验室制备的银/氯化银电极来监测混凝土中的氯离子含量,测试了电极的响应性能和长期稳定性,研究了总氯离子含量与自由氯离子含量之间、总氯离子含量与电位之间的关系。结果表明:银/氯化银电极电位能比较好地监测到混凝土中氯离子含量变化的过程,具有良好的长期稳定性能。总氯离子含量随自由氯离子含量的增加而增加,两者之间呈现幂函数的规律。总氯离子含量随电位上升而下降,两者之间呈指数函数的规律。

Abstract: Wet-dry alternation permeation was used in this experiment. The Ag/AgCl electrode manufactured by laboratory was chosen to monitor the content of the chloride ion in concrete. Response performance and long-term stability of the Ag/AgCl electrode were also studied. The relation of total chloride with free chloride, and the relation of total chloride with electrode potential were also studied. Results revealed that the change of the chloride ion content in concrete can be monitored well by the Ag/AgCl electrode potential. The Ag/AgCl electrode has a good long-term stability. The total chloride increases with the addition of free chloride. The power function can be used to describe the relationship of total chloride and free chloride. The total chloride decreases when the potential increases. The exponential function can be used to describe the relationship of total chloride and electrode potential.
Key words:  wet-dry alternation method    Ag/AgCl electrode    monitor    chloride ion content
