INFLUENCE OF DESALINATION ON MECHANICAL BEHAVIOR OF PRESTRESSED CONCRETE MEMBERS

Abstract

Recently, premature deterioration of concrete structures due to chloride induced corrosion of reinforcement has become serious problem. Desalination is aimed to remove chlorides from concrete structures and expected as the fundamental repair method. Desalination has been applied to RC structures positively but the application to PC structures has been considered difficult because of the hydrogen embrittlement problem. This paper describes the influences of desalination on both behavior of prestressing steel bars and PC beams.
