The invention is concerned with protection of steel bars (10, 11, 12) embedded in concrete (17) against corrosion. The bars, prior to embedding, are coated with a physical barrier, typically epoxy resin. Discontinuities occur inevitably in such barriers. Cathodic protection against corrosion is provided at the discontinuities by an anode (18) connected to the bars such that the bars become cathodic at the discontinuities. |
