评价混凝土中钢筋腐蚀的恒电量技术

本文综述了恒电量技术在混凝土中钢筋腐蚀上的应用研究，和其他化学技术相比较，可以认为恒电量技术具有测量速度快，反应灵敏，无损检测和近乎原位的腐蚀测量以及不受介质阻力影响等优点，恒电量技术在研究钢筋的腐蚀中有着良好的应用前景，同时这种方法目前也还存在着有待解决的几个难点。

The Coulostatic Method for Evaluating Corrosion in Reinforced Concrete

In the present paper, the application of the coulostatic method to the corrosion of steel in concrete was reviewed. By comparing with other electrochemical techniques, the results obtained in the previous work reveal that the coulostatic method is an interesting alternative to the usual procedures for estimation of corrosion rate, and is better than them in some respects. The main advantages are as follows. The signal to be used can be instantaneous and as small as desired, so the electrode is minimally perturted during the measuring process. In addition, it is as rapid and quantitative, and at least as reliable due to the lower risk of the electrode being perturted. All of those factors are shown that the coulostatic method may be a good tool to assess the corrosion information of steel in concrete, however it still has some difficulties to apply in_situ. Furthermore, some suggestions on developing were also put forword.
