Impedance spectroscopy – comparison of dielectric model with experimental results

Abstract Impedance measurements of building materials have been gaining popularity especially in the last twenty years. No electrical component has only resistance, capacitance or inductance, as there is an interplay these parameters. This compounded case materials, which contain a significant number different phases that vary chemical composition, crystalline structure and properties. It is, therefore, necessary to choose connection measurement system provides most accurate information about material. primarily meant include complex impedance, its components quantities derived from them. The are resistance capacitance. Using we can point out composition material, conductivity identify percolation threshold describe sensory properties more detail. For measurements, alternating electric field crucial, range frequencies depends on instruments used. characterization, used frequency 100 Hz kHz; however, measure down 1 MHz.
