摘要: Abstract Corrosion monitoring of reinforced bar is critical for evaluating the safety and durability concrete structures. The aim this paper to introduce a novel electro-magnetic apparatus (EMMA) that can be used monitor corrosion in concrete. 24 Hall-effect sensors are mounted on EMMA with linearly arrangement an enlargement probe also equipped, by which magnetic field intensity variation bar/concrete interface detected. For comparison, traditional electro-chemical impedance spectroscopy was recorded. As results shown, flux changed when occurred bar, further induced increase voltage at cross section With information voltage, damage identification orientation recorded EMMA. This analyze time-dependently.
