Description

technical field [0001] The invention relates to the field of steel bar corrosion detection, in particular to a multifunctional concrete structure steel bar corrosion rate detector and a detection method. Background technique [0002] The corrosion process of most reinforced concrete structures is the process of electrochemical reaction, so most of the methods of electrochemical analysis are used to study the corrosion of steel bars. The parameters related to the corrosion state of steel bars can be obtained by electrochemical methods, such as the corrosion potential of steel bars, the corrosion current density (corrosion rate) of steel bars, the electric double layer capacitance of the interface between concrete and steel bars, and the charge transfer resistance. According to these parameters, it can be judged Corrosion of steel bars. However, the traditional electrochemical detection method has problems such as complex operation, cumbersome data processing, large detection...

AI Technical Summary

Problems solved by technology

However, the traditional electrochemical detection method has problems such as complex operation, cumbersome data processing, large detection error, and long detection time;

[0003] At present, the steel bar corrosion detector also has a single test parameter and inaccurate test results; the test needs to slightly break the concrete to expose the steel bar to be tested and connect with one pole of the test equipment, which will have a certain impact on the concrete; the test result can only be done for the corrosion of the steel bar. Qualitative judgment, not quantitative judgment
