Description

Technical Field

[0002] Concrete is the most widely used and consumed building material in infrastructure construction, including water conservancy projects, industrial and civil buildings, roads and bridges, and ports. Its quality often determines the safety of the entire project, and any problems can pose a serious threat to the lives and property of the public. Therefore, controlling concrete quality is crucial. Concrete is typically doped with chloride ions, which can adversely affect concrete and steel, reducing its overall durability. In environments with high chloride ion content, steel bars corrode, and the corrosion products expand, damaging the concrete structure and preventing it from maintaining safety and stability for the required period. Therefore, measuring the chloride ion concentration in concrete is crucial, and sensors are required to regularly monitor the chloride ion concentration in concrete.

[0003] In the prior art, the chloride ion corrosion path and distribution in concrete structures are complex and changeable.

Since the position of the sensor cannot be adjusted, omissions may occur, resulting in some key areas with high chloride ion concentrations not being detected. As a result, it is impossible to comprehensively and accurately assess the overall chloride ion corrosion status of the concrete structure, and it is impossible to take effective protective measures in a timely manner. Therefore, a concrete chloride ion corrosion detection sensor is proposed. Summary of the Invention
