On decrit une nouvelle methode de mesure de la resistivite electrique du beton dont la technique est basee sur un travail ancien de J. Newman, qui avait calcule la resistivite entre un disque et une electrode auxiliaire placee a l'infini. Comparee a la methode de Wenner, cette methode presente l'avantage de n'utiliser, pour les mesures, qu'une petite electrode. Dans cet article, on presente les resultats de la comparaison etablie avec la methode de Wenner et avec les resultats obtenus avec une c...

Concrete provides to steel a long-term protection due to the alkalinity of the cement and to the physical isolation that the cover represents. However, when the carbonation front or the chloride ions reach the rebar, the steel develops an active corrosion which is detrimental towards the structural behavior. The consequences of the reinforcement corrosion are: (a) A decrease of the steel cross-action, (b) the possible loss of steel ductility, (c) the cracking of the cover, and (d) the loss of th...

Le besoin pressant se fait sentir partout dans le monde de disposer de methodes in situ pour detecter le taux de deterioration dans les constructions en beton arme. On propose deux nouvelles methodes derivees de la methode de resistance de polarisation, mais qui different de celle-ci en ce qu'elles peuvent s'appliquer aux structures elles-memes, malgre la distribution non uniforme des signaux electriques dans ces dernieres. Les deux methodes proposees sont d'une simplicite et d'une surete compar...

In the present paper the similarities and differences between the systems steel/atmosphere or soil and steel/concrete are analyzed. The differences are related to the passive state of reinforcement embedded in non-carbonated and chloride free concrete. The similarities, when carbonation or chloride ions break down the passive film, are discussed. In these conditions the environmental relative humidity plays a decisive part in the corrosion kinetics of the reinforcing steel. The effect of environ...

In 1987 the authors published their first paper on the possibilities of on-site measurement of rebar corrosion rate. In that paper the transmission line model was applied in order to calculate the critical length reached by an electrical signal along a rebar and therefore, the corrosion rate by unit of metal and concrete surface. Other papers have been recently published based in the same transmission line model. In the present paper the experimental errors which the guard ring induces, are comm...

Abstract Corrosion potential mapping is a useful qualitative technique for measuring the risk of corrosion for reinforcements. However, occasionally this requires not only knowing whether or not th...
