摘要： PROBLEM TO BE SOLVED: To provide a nondestructive inspection method and device of a degree of reinforcement steel corrosion in a concrete structure by an ultrasonic method for quantitatively detecting the degree of corrosion by non-destruction.
SOLUTION: In the nondestructive inspection method of the degree of reinforcement corrosion in concrete, the degree of corrosion is determined with an addition spectrum SS(f). In this case, the addition spectrum SS(f) is determined by: (1) processing of averaging the reflected wave from the reinforcement to determine an averaged waveform F
n (t); (2) processing of extracting wave forms at a time interval including reinforcement reflected wave in the averaged waveform F
n (t) and determining a formation waveform FF
n (t); (3) processing of converting the formation waveform FF
n (t) into a frequency region with an FFT, and determining a power spectrum S
n (f); and (4) processing of determining an addition spectrum ΣS
n (f) (n=1-k).

摘要： PROBLEM TO BE SOLVED: To simply measure the depth of a neutralized portion without causing the breakage of a concrete structure or its second drilling.
SOLUTION: A drilled hole is made in the concrete structure 10 by using a drill 1. With an insert rod 2 including a transfer agent inserted into the drilled hole, and left standing for several to ten seconds or more, then the insert rod 2 is pulled out. In this event, the color of the transfer agent is changed in a portion disposed on a not-neutralized portion of the insert rod 2. A length is measured from a portion positioned on an opening end of the drilled hole to the discolored portion of the insert rod 2, thereby obtaining the depth of neutralization.
