Abstract:The reinforced concrete structures have been considered durable for at long time. But recently, it has been reported that they are deteriorated by reinforcement corrosion to be suffered from chloride attack. Desalination, which is an electrochemical treatment of chloride extraction from concrete, has been developed as an essential repair method. Steel bar embedded in concrete acts as a cathodic electrode through desalination process and sodium ions are gathered about the steel bar.
