Abstract[English]
The invention relates to a method for assessing corrosion phenomena on at least one metal element (1) of a concrete structure (2) covered at least in regions with a material (3) that is electrolytically conductive or can be made electrolytically conductive, in which an electrolyte volume (4) is positioned within the material (3), an electrode (5) is arranged in the electrolyte volume (4) so that the electrode (5) and the electrolyte are in electrically conductive connection, and the electrolyte volume (4) is brought into electrically conductive contact with the material (3), and an electrochemical measurement indicative of a state of corrosion on the metal element (1) is carried out. The invention also relates to a device (11) for assessing corrosion phenomena on at least one steel element (1) of a concrete structure (2) covered at least in regions with a material (3) that is electrolytically conductive or can be made electrolytically conductive.[French]
L'invention concerne un procédé d'évaluation de phénomènes de corrosion sur au moins un élément métallique (1) d'une structure en béton (2) recouverte au moins par endroits d'un matériau (3) électrolytiquement conducteur ou pouvant être rendu électrolytiquement conducteur, un volume d'électrolyte (4) se trouvant à l'intérieur du matériau (3), une électrode (5) étant disposée dans le volume d'électrolyte (4) de manière à ce que l'électrode (5) et l'électrolyte soient en liaison électriquement conductrice, le volume d'électrolyte (4) étant mis en contact électriquement conducteur avec le matériau (3), et une mesure électrochimique indiquant l'état de corrosion de l'élément métallique (1) étant effectuée. L'invention concerne également un dispositif (11) permettant d'évaluer les phénomènes de corrosion sur au moins un élément en acier (1) d'une structure en béton (2) recouverte au moins par endroits d'un matériau (3) électrolytiquement conducteur ou pouvant être rendu électrolytiquement conducteur.
