Performance assessment of specialist conductive paint for cathodic protection of steel in reinforced concrete structures

Research output: Contribution to journalArticle


ICCP system provides effective corrosion protection in a chloride environment. This research evaluates the feasibility of zinc rich paints (ZRP) as ICCP anode for RC structures. The preliminary investigation showed the application of three layers of ZRP with medium concrete surface roughness and use of Cu/Nb/Pt wire as primary anode gives maximum bond strength and uniform current distribution across the ZRP coating. Moreover, polarization results showed satisfactory performance of the ZRP anode coating subjected to a current density of 12.5 mA/m2. The anode was found to be vapour permeable and effectively provide protection with a service life of up to 15 years.
