Abstract
The ratio of the standard deviations of oscillations in the corrosion potential and open-circuit current about their mean values has been used lately for calculating the noise polarization resistance (R p, noise ). In this work, the ability of this method to obtain quantitative information on the corrosion rate of steel reinforcements embedded in concrete was analysed. In addition, the discriminating capacity of electrochemical noise as regards active and passive zones in reinforcements containing both was investigated.
Résumé
Le rapport des écarts types sur la valeur moyenne des oscillations du potentiel de corrosion et de l'intensité du courant en circuit ouvert a été utilisé récemment pour le calcul de la résistance de polarisation du bruit (R p, noise ). Dans cet article, on analyse l'utilisation de cette méthode pour obtenir des informations quantitatives sur le taux de corrosion des armatures enrobées dans du béton. On analyse également dans quelle mesure le bruit électrochimique peut différencier les zones actives et passives des armatures.
