| Abstract | STEEL-REINFORCEMENT corrosion can be mitigated by cathodic protection. In order to deliver the protective cathodic current to the rebars, a conductive anode material must be applied to the surface of the protected concrete structure. The performance of two metallized-zinc coating anodes and two conductive paints was investigated. Bond strengths were found to slowly decrease as the current density and the length of the polarization period increased. On the other hand, driving voltages across all coating anodes were found to increase. Evidence of acidification at the anode/concrete interface was only significant for the conductive paints. Arc-sprayed zinc performed well in this three-year research programme, although it was outperformed by one of the conductive paints. Arc-sprayed zinc aluminium (85:15) performed poorly, and is not recommended as an impressed-current anode. |
