Abstract

L'invention concerne un procédé de traitement d'une structure en béton comprenant au moins une surface accessible (3) et au moins une armature en acier (2). Selon le procédé, on applique un champ électrique entre l'armature en acier (2) et la surface accessible (3) de manière à provoquer une migration de cations vers la surface accessible (3) et une migration d'anions vers l'armature en acier (2).

Figure imgaf001
The invention relates to a method for treating a concrete structure comprising at least one accessible surface (3) and at least one steel reinforcement (2). According to the method, an electric field is applied between the steel reinforcement (2) and the accessible surface (3) so as to cause migration of cations to the accessible surface (3) and anion migration to the reinforcement steel (2).
