Acoustic-electric transformations in model solid samples of cement-sand mixture in contact with aqueous salt solutions

Abstract

This paper presents the results of experimental studies of the parameters of electromagnetic signals based on acoustic-electrical transformations during contact of samples of hardened cement-sand mixture with aqueous solutions of salts. The regularities of changes in the parameters of electromagnetic signals and their spectra during excitation of such contact by deterministic acoustic pulses are determined. Based on a comprehensive analysis of the obtained results, a new method for determining the degree of penetration of salt solutions into porous materials is proposed. The possibility of quantitative assessment of mineralization of natural waters by identifying changes in the parameters of electromagnetic signals during the interaction of salt solutions with porous solid samples is shown. In addition, the applicability of the considered method for monitoring the defectiveness of dielectric porous materials is shown.
