ABSTRACT
The ultrasonic inspection of concrete corrosion thickness adopted plane testing method, assume that the spread of ultrasound in corrosion and corrosion layer velocity is a constant value (Tian & Wu 2005, Fan et al. 2012). Detection methods such as shown in Figure 1, the emission transducer T is placed in a point away from the beam end remains unchanged, the receiving transducer is placed in the B1, B2, B3 and other locations along the surface of the concrete with a certain distance continuous scanning, read the corresponding sound as ti.. In order to ensure the transducer and the concrete surface is equal to the pressure, the two transducers are respectively applied for 2 kg force.
