Risultati finali New and replaceable anodes for concrete protection The project aim was to develop and prove that a cathodic protection (CP) system for new reinforced concrete structures is both economic and practical. Reinforced concrete, often used in housing and industrial construction, fails due to corrosion of the steel reinforcement underneath. One way to enhance the lifetime of the reinforced concrete structures is to employ an electrochemical method, CP. Unfortunately current CP systems have found limited use and current anodes are expensive and difficult to maintain and install. The new CP system described in this project features low-cost installation and ease in replacement in both old and new structures. A new-pulsed power supply has a patent pending and is being further evaluated through other industrial trials. This pulsing allows a huge saving in the number of anodes on a structure with a consequent dramatic increase in the applicability of CP to new structures. The second innovative part of the research is to provide removable and replaceable anodes in pockets in the new concrete structure. New anodes have been developed with this replaceability in mind and these are coupled to the concrete with a gel. This gel is non-toxic, acid resistant, ionic conductive, and is a significant step forward in the state of technology currently available. G&K are currently engaged in long-term field trials and feel confident that this research program will lead to commercial products, which have considerable sales potential within and outside the EU.
