Corrosion Monitoring of Reinforced Concrete Structure Based on Electrochemical Theory

Reinforced concrete structure is the most used in modern and contemporary architecture. Steel corrosion is an important reason for the instability of the steel structure, which can decrease the durability of the steel structure and cause loss of property and personnel. Therefore, it is very important to monitor the corrosion of reinforced concrete structure. The electrochemistry theory is the most effective method to realize the corrosion monitoring of reinforced concrete structure. Based on the electrochemistry theory and experiment, the problems of corrosion monitoring of reinforced concrete structure are studied in depth. The main content of this paper is divided into two parts: First, based on the transfer function and complex function, the time domain response characteristic analysis algorithm for corrosion of reinforced concrete structure is effectively established in uniform corrosion. Second, in the aspect of local pitting corrosion, the energy spectrum characteristics of the electrochemical corrosion noise of the 3D ultra-depth video of the reinforcement pitting corrosion are studied by wavelet energy spectrum algorithm. A three-dimensional cellular automaton prediction method is established, and the accuracy is verified by the experiment.
