摘要: 冻融循环作用后,混凝土内部发生损伤,混凝土的质量损失增加,超声波速、抗压强度和劈裂抗拉强度下降;而随着冻融循环作用次数的增加,钢筋与混凝土的粘结强度下降,钢筋自由端的峰值滑移量则增大;通过对3种直径螺纹钢筋与混凝土冻融后的粘结性能的试验研究得出:冻融循环作用后钢筋与混凝土粘结性能下降,特别是极限粘结强度随着冻融循环作用次数增加而下降,根本原因是由于冻融作用损伤混凝土造成混凝土的强度下降所致。

Abstract: Frost damage appeared in concrete after freezing and thawing,its mass loss was increased,while ultrasonic velocity,compressive strength and splitting strength were decreased.With the increasing of freezing and thawing cycles,the bond strength between steel bar and concrete was decreased,and ultimate slippage at free end of the steel bar was increased.Based on the test results,the bond behavior was deteriorated after freezing and thawing,whose main reason was the decrease in concrete strength by damage of concrete due to freezing and thawing cycles.
