Abstract

In this study,pull-out tests are carried out to research the bond behavior between steel bar and frozen concrete during winter construction.Test parameters are construction temperature,amount of anti-freezing admixture and curing condition.load-slip curve of steel bar and concrete is obtained,and factors such as ultimate bond strength and bond slip are analyzed and compared with specimens in standard curing condition.The test results show that bond properties between steel bar and concrete are degenerated due to inadequate amount of anti-freezing admixture and poor curing condition in low temperature.
