Abstract

In this research, a new type of corrosion monitoring technique for reinforce concrete was developed. The technique used piezoelectric sensors to detect the ultrasonic signals during corrosion. The mechanism of the method was presented. Experiment was carried out to monitor the corrosion process using piezoelectric sensors. The corrosion was also monitored using stain gauge for comparison.

Keywords: Concrete, corrosion, piezoelectric sensor, steel bar, ultrasonic.
