活性粉末混凝土与高强钢筋的黏结性能试验研究

Research on Bond Behavior of Reactive Powder Concrete and High-strength Reinforcement

为了探究活性粉末混凝土与高强钢筋的黏结性能,通过不同直径、不同埋长以及不同埋置位置的HRB500钢筋的拔出试验,分别探究钢筋直径、钢筋埋置长度及混凝土保护层厚度对黏结性能的影响,从而回归出高强钢筋与活性粉末混凝土的黏结公式。

In order to explore the bond behavior between reactive powder concrete and high-strength reinforcement, this article researches the pull-off test for HRB500 reinforcement with the different diameters, different buried length and different embedded position to analyze the influence of reinforcement diameter, embedment length and thickness of the protective layer＇ s on the bond behavior. The bond formula of the high-strength reinforcement and reactive powder concrete are obtained.
