“…developed a method to detect the environmental deterioration of the structure by measuring the decrease in residual magnetization on probes embedded in mortar. 24 Analogous to crack inspection using magnetic methods, metallic loss or other irregularities caused by corrosion can be inspected via magnetic leakage methods. 25 More work needs to be carried out to industrialize corrosion monitoring technology through measuring and mapping of magnetic fi elds.…”

This paper investigated the evaluation of the concrete damage degree due to steel bar corrosion for reinforced concrete structures. Brillouin optical fiber time domain analysis (BOTDA) sensors were developed to monitor the steel bar corrosion expansion strain. Electrochemical accelerating experimental results showed the sensors could be used for early detection and the lifelong monitoring. The damage factor was proposed to quantitatively evaluate the concrete damage degree before initial cracking and during the development of cracks. Finite element analysis was performed on concrete specimens to map the monitoring results with the damage factor, which supported the capability of the damage factor.
