| Résumé : | This paper deals with results of electrochemical measurements carried out on reinforced concrete slabs. Measurements were performed four times a year over a period of two years by means of three kinds of device: a Gamry© laboratory potentiostat, and Gecor6© and Galvapulse© on-site apparatuses. Results showed that all devices are able to detect passive corrosion. They coherently diagnose chloride-containing-slabs and can detect the depassivation of rebars. The variability of the depassivation time was pointed out as far as chloride-induced-corrosion is concerned. Conversely, corrosion levels proposed by the three devices are different in the case of carbonation (generalised)-induced corrosion, even if all of them detect the active corrosion state. This discrepancy showed that the use of these results in term of steel loss is not possible. |
