ABSTRACT:
Disclosed is a method for the cathodic protection (KKS) of the reinforcements of ferroconcrete edifices against corrosion. According to said method, a) one side of the structural joints of the concrete supporting elements is sealed, b) the KKS anodes are introduced into the structural joints, c) an ionically conductive gel is introduced into the joints that are closed on one side, and d) the structural joints are optionally sealed as a whole. Surprisingly, the required electrical conductivity can be reliably ensured during the entire application period with the aid of the ionically conductive gel, which is a prerequisite for effectively and reliably protecting the steel reinforcements of concrete structures against corrosion.
