Research on Magnetic Induction Detection of Steel Bars Corrosion

Abstract

Abstract Reinforced concrete structures are widely used in modern buildings. However, the structural damage caused by the steel bars corrosion seriously affects the building remaining life. The reinforcement corrosion in concrete is slow, so the long-term detection of reinforcement corrosion is very important. The development of reinforcement corrosion detection equipment in China is slow, which cannot meet the application requirements of domestic concrete structures, this paper proposes a non-contact magnetic induction detection method for reinforcement corrosion. Through theoretical analysis and experimental design, a simple model is built and simulated. Simulation results of single and multiple steel bars corrosion to verify the feasibility of the method. This paper provides theoretical support and technical solutions for the operation state detection of non-contact reinforced concrete, and makes contribution to the non-contact magnetic induction detection technology.
