Abstract：The main focus is the state-of-the-art magnetic flux leakage(MFL)detection technique for rebar corrosion characteristics in reinforced concrete(RC)structures,providing a comprehensive analysis of relevant research.The results indicate that the MFL detection technique can accurately identify corrosion areas of rebar embedded in RC structures and quantitative assessment the corrosion degree of the rebar.To further improve the applicability and accuracy of using the MFL detection technique for corrosion characteristics in existing RC structures,the probabilistic distribution characteristics of corrosion degree assessments resulting from the random distribution of magnetization should be fully considered,the effects of stress,fatigue,stirrups/adjacent longitudinal rebars,corrosion products,and concrete should be clarified,and the application of computer vision for automatic identification based on MFL imaging and the integration of multiple indicators and methodologies needed be promoted.
