Abstract

The availability of on-site methods of diagnosis of the deterioration rate in reinforced concrete structures is a pressing technical need all over the world. Two new methods are proposed in this paper which are derived from the polarization resistance method, but which, differing from this method, are applicable to full-size structures, in spite of the non-uniform distribution of the electric signals in them. The two proposed procedures are of a simplicity and reliability comparable with those offered by direct measurement of polarization resistance.

Resume

Le besoin pressant se fait sentir partout dans le monde de disposer de méthodesin situ pour détecter le taux de détérioration dans les constructions en béton armé. Dans cet article, on propose deux nouvelles méthodes dérivées de la méthode de résistance de polarisation, mais qui diffèrent de celle-ci en ce qu’elles peuvent s’appliquer aux structures elles-mêmes, malgré la distribution non uniforme des signaux électriques dans ces dernières. Les deux méthodes proposées sont d’une simplicité et d’une sûreté comparables à celles offertes par la mesure directe de résistance de polarisation.
