摘　　要：本文通过将混凝土结构用钢筋放置于腐蚀介质(PH=4～5弱酸性溶液)环境中,对不同腐蚀程度的钢筋进行强度和伸长率等力学性能试验,并将试验结果与未经腐蚀的钢筋对比,探讨腐蚀对钢筋力学性能的影响.In this paper, the mechanical properties of reinforcing bars u nd er the case of no corrosion and weak acid corrosion are tested and analyzed. The test results aer compared to uncorrosible reinforcing bars to discover the in flucnce of corrosion to the reinforcing bas' mechanical properties.
