摘要

The correlation between the concentration of defects such as artificial air voids in concrete and the parameters of the electrical response to impact was examined. It was shown that the frequency shift that corresponds to the maximum cross-correlation coefficient between the spectra of electrical responses of defective and non-defective samples may be used as a diagnostic criterion for determining the concentration of air voids in concrete.
