Title: Sacrificail Cahodic Protection of RC-Structures Using a Zinc-Hydrogel Anode-Investigations on the Effectiveness
Author(s): M. Raupach and M. Bruns
Publication: Special Publication
Appears on pages(s): 127-142
Keywords: cathodic protection; reinforcement corrosion; sacrificial anode; zinc-hydrogel
Abstract:Cathodic protection is used world-wide to protect reinforced concrete structures against reinforcement corrosion. Cathodic protection systems can generally be divided into impressed current systems and systems working with sacrificial anodes. The Zinc-Hydrogel Anode is one of these sacrificail anode systems. This paper presents investigation on the effectiveness of the Zinc-Hydrogel Anode to control rinforcement corrosion. The aim of this investigation was to find out how parameters like reinforcement content and position of the anode are affecting the effectiveness. As a result it was found, that the protection current density and the polarisation of the reinforcement are highly affected by both parameters.
