Corrosion monitoring of steel rebars in concrete structures by AC impedance method
Corrosion monitoring by AC impedance has been investigated to evaluate on-site corrosion rates of concrete reinforcing steel bars and to estimate the service life of concrete structures. A new corrosion monitoring method has been developed to measure the corrosion rates of rebars in only a short time. It takes only a few minutes to obtain a corrosion rate for rebars by measuring impedance at two frequencies. Furthermore, portable-monitoring apparatus has been successfully made for the purpose of on-site measurements of corrosion rates of rebars. This apparatus was applied to rebars in real concrete structures. Corrosion rates estimated by this apparatus had an almost linear correlation with measured corrosion rate. These results proved that this newly developed method and apparatus are able to evaluate on-site corrosion rates of rebars in real concrete structures.
