| Abstract |
A corrosion diagnosis using a complex resistivity method measures the corrosion level of reinforcing bar without removing concrete covers compared to that of the existing polarization resistance method. This non-destructive method, which can diagnose the corrosion of reinforcing bars largely depends on the electrode spacing which represents different measurement regions. Therefore, the purpose of this study is to examine the influence of the electrode spacing with the consideration of the measurement of complex resistivity and to discuss the relationship between the electrode gaps and the reinforcing bars erected in concrete. And this study investigates the change of complex resistivity with the development of corrosion using an electrolytic corrosion test in order to grasp the mensurability of corrosion. In addition, this study makes an empirical investigation into the influence of the chloride permeated in the specimen on the measurement of resistivity in a corrosion test using the electrolytic corrosion test at a laboratory level. |
