Abstract: In order to discuss the bond problems after corrosion,this paper studies degradation of bond behavior between corroded steel strands and cement slurry based on the background of chlorine salt environment.Through experiments,we get bond characteristics of corroded steel strands and cement slurry.Through analyzing the test data,we get bond-slip curves of specimens of different crack width and their bond behavior parameters.Results show that there is no obvious degradation relationship between the ultimate bond strength of specimens and their corrosion degree,ultimate bond-slip volume and residual bond-slip volume of corroded steel strands and cement slurry specimens both present a downward trend with the increase of corrosion degree,but they have not obvious linear relation.
