摘要

本文介绍了硬化水泥-砂混合料试样与盐水溶液接触时基于声-电变换的电磁信号参数的实验研究结果。确定了在确定性声脉冲激励下电磁信号参数及其谱的变化规律。在综合分析所得结果的基础上，提出了一种测定盐溶液对多孔材料渗透程度的新方法。揭示了通过识别盐溶液与多孔固体样品相互作用过程中电磁信号参数的变化来定量评价天然水体矿化的可能性。此外，还说明了所考虑的方法对介电多孔材料缺陷监测的适用性。

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

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.
