Description

technical field [0001] The invention belongs to the technical field of building structure monitoring, in particular to an intelligent monitoring system and method for the corrosion state of steel bars in concrete. Background technique [0002] Seawater is a strong electrolyte solution containing corrosive salts. Reinforced concrete construction projects in the marine environment are vulnerable to damage during a long service period. The intrusion of microelements such as chloride ions in seawater leads to carbonation of concrete and internal reinforcement. Corrosion, the volume of corroded steel bars continues to expand, and the resulting expansion stress causes cracks in carbonized concrete, which further intensifies the penetration of erosive ions in seawater and accelerates the damage to buildings in marine environments. Among them, the corrosion of steel bars inside concrete is the cause Therefore, it is extremely important to establish a system that can monitor the corr...

Problems solved by technology

[0006] The problem at this stage is that the electrochemical parameters measured by the temperature and humidity macro-cell have a certain influence, and there is a coupling relationship between the corrosion characteristics. Each measurement result needs to rely on expert experience to determine the degree of corrosion, which is difficult to deploy on conventional terminal equipment.
