Condition assessment of concrete in hydraulic structures by surface wave non-destructive testing

For 3 samples (969, 910, and 909) 2 graphite fractions (one close to the sample, and one far from the sample) were extracted from the graphite capsule, using the

After extraction of the lateral wave in the received signal using the matching pursuit method, the phase velocity dispersion characteristic is determined, and concrete cover

Figure 3 : Receiver signal at position 1.5 cm offset As shown in Fig.3, the received signal is composed of surface wave, diffracted waves, reflected waves and
