CATHODIC PROTECTION SYSTEMS

摘要

A cathodic protection system to protect the reinforcement bars in concrete wherein there is provided as an anode a hydraulically porous material bonded to the concrete so that the anode can be irrigated by water to reduce chloride concentration. A preferred material for the anode is TiOx in bulk coherent form where x is in the range 1.6 to 1.9 preferably 1.67 to 1.85.
