Corrosion of steel bar is one of key factors undermining reinforced concrete (RC) structures in a harsh environment. This paper attempts to review the non-destructive procedures from the aspect of the corrosion measurement techniques, especially their advantages and limitations. Systematical classification of diagnostic methods is carried out to determine any probable corrosion issues before the structures become severe, and helps choose the suitable method according to different construction features. Furthermore, the three electrochemical factors method is introduced to inspire researchers to combine various techniques to improve corrosion evaluation accuracy. The recommendations for future work are summarized, in conclusion.
钢筋的腐蚀是恶劣环境下破坏钢筋混凝土（RC）结构的关键因素之一。本文试图从腐蚀测量技术的角度来回顾无损检测程序，特别是它们的优缺点。对诊断方法进行系统分类，以便在结构严重恶化之前确定可能存在的腐蚀问题，并根据不同的施工特点选择合适的方法。此外，还介绍了电化学三因子法，以启发研究人员结合各种技术来提高腐蚀评估的准确性。最后总结了对未来工作的建议。
