Monitoring corrosion of steel bar using ultrasonic guided wave

摘要

The reinforcement corrosion was monitored using ultrasonic guided wave. The amplitude of ultrasonic guided wave could response the degree of reinforcement corrosion. The experiment was carried out to monitor the corrosion process. And the results indicated that ultrasonic guided wave could monitor reinforcement corrosion in reinforced concrete structure real-timely and online. It could reflect the degree of reinforcement corrosion effectively.
