摘要： PROBLEM TO BE SOLVED: To provide a nondestructive concrete strength measuring apparatus capable of easily performing measurement with a high measurement precision and to provide its measuring method. SOLUTION: A reinforcing bar 2a in a concrete block 2 is irradiated with a magnetic field pulse from a surface 2b of the concrete block 2 to excite the reinforcing bar 2a and generate sound from the reinforcing bar 2a as a sound source. A propagation delay time required for the sound to reach an acoustic converter 5, a point of measurement in the surface 2b of the concrete block 2, is measured. The velocity of the sound is determined from the propagation delay time and the distance between the reinforcing bar 2a and the point of measurement 5. From the sound velocity and the correlation between previously determined concrete strength and the sound velocity, the compressive strength of the concrete 2 is estimated. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a nondestructive diagnostic method for simply and accurately diagnosing the degree of corrosion of a rebar contained in a reinforced concrete construction. SOLUTION: A rebar contained in a reinforced concrete construction is excited, by having a surface of the reinforced concrete construction irradiated with electromagnetic pulses. Sounds coming from the rebar are received by the surface of the reinforced concrete construction. A waveform of the sounds thus received is analyzed. A spectrum is obtained by Fourier transformation of the waveform of the sounds thus received. The spectrum is separated into a low-frequency component and a high-frequency component. Corrosion of the rebar is diagnosed from the ratio between the area S L of the low-frequency component and the area S H of the high-frequency component. COPYRIGHT: (C)2010,JPO&INPIT
