Investigation of Complex Electrical Properties of Concrete during Decommissioning of Nuclear Power Plants: An Experimental Analysis

Electrical impedance spectroscopy (EIS) is a powerful technique for characterizing the electrical properties of materials and systems. EIS involves the measurement of complex impedance and can provide valuable insight into inhomogeneous cementitious materials, including the sensitivity to moisture content. Therefore, this work contributes to the determination of moisture content (MC) in concrete composites. A comprehensive study of the complex electrical properties of concrete was performed experimentally in a frequency range between 10 Hz and 10 MHz implementing impedance spectroscopy.
