摘要

The main difficulty for the application of R_p on site is the vanishing of the current with the distance which has been overcome with the use of a modulated confinement of the current only feasible if the guard ring is monitored during the measurement by means of electrodes able to detect the distance reached by the current. In the present paper after a short review of existing corrosion rate meters to measure on site, results of a comparison made of reinforced concrete slabs with various degradations such as car-bonation or chloride among several using a guard ring with modulated confinement of the current is presented in order to have a reproducibility and repeatability for the measurements. Results show a good correlation among all the methods used for the corrosion rate evaluation.
