Description

technical field [0001] The invention relates to a monitoring system, in particular to a reinforced concrete corrosion monitoring device. Background technique [0002] Reinforced concrete has many advantages such as high tensile and compressive strength, good durability and fire resistance, and low cost, and is widely used in bridges and buildings. However, due to the influence of climatic conditions, chlorides, etc., the steel bars in it will corrode. [0003] When the steel bar corrodes, the rust spreads, cracks the concrete and loses the bonding force between the steel bar and the concrete, resulting in a significant reduction in the tensile and compressive strength of the reinforced concrete. However, the corrosion process of steel bars in concrete is slow, so continuous monitoring of steel bar corrosion is required. [0004] At present, the commonly used detection methods mainly include: analytical method, physical method and electrochemical method. [0005] The analy...

AI Technical Summary

Problems solved by technology

[0007] The electrochemical method mainly judges the corrosion of steel bars by measuring the concrete resistivity, steel bar corrosion current and voltage, which is easily affected by humidity and ion concentration, and the results have large deviations, and online in-situ detection cannot be performed;

[0008] The above methods have disadvantages such as cumbersome detection methods and operations, low monitoring efficiency, incapable of continuous monitoring, and incapable of real-time analysis.
