A galvanic zinc-hydrogel system for cathodic protection of reinforced concrete structures

Süoss, B.M.J.C. / Hondel, A.J. van den / Hondel, A.W.M. van den

The Zinc-Hydrogel Anode system consists of a Zinc foil bonded to an ionically conductive Hydrogel adhesive, which is applied directly to the surface of the steel-reinforced concrete. A copper wire connects the zinc anode to multiple steel rebars. The performance is monitored by measuring the current flow in the wire, by measuring the amount of zinc consumed or, more generally, by taking depolarisation readings at regular intervals. All of these measurements are an indication of the performance of the galvanic system and the corrosion of the steel rebars that is being prevented. The galvanic Zinc-Hydrogel system has been installed in the field on a variety of concrete structures in different environments to determine the overall performance. This paper will give examples on the installation of 2 of these systems in detail including monitoring data that ncontains performance readings for at least 12 month period of active service.
