The use of electrochemical chloride extraction (ECE) has in recent years become an accepted technique for the rehabilitation of reinforced concrete structures subject to chloride attack. The technique has primarily been applied to structures where the chloride ions have ingressed from the external environment and have not progressed much beyond the first layer of reinforcement. However, the technique also has the potential to be applied to structures containing cast-in chlorides or structures where the chloride ions have progressed significantly beyond the first layer of reinforcement. To study the effect of applying desalination to this type of contaminated structure specimens have been cast with reinforcing steel at 50mm and 100mm centres and chloride levels at 3% by weight of sample. The percentage chloride extracted and the extraction profiles are presented.
