AC impedance spectroscopy to characterize the dielectric material properties in concrete during decommissioning of nuclear power plants

Nurjahan, T.; Schleicher, E.; Hampel, U.

Abstract

Electrical impedance spectroscopy (EIS) is a powerful technique to study material properties, e.g., it is highly sensitive to the moisture content of inhomogeneous cementitious materials. This study contributes to the in-situ measurement of the moisture content (MC) in concrete during the decommissioning of nuclear power plants. Thus, a comprehensive investigation of dielectric material properties of concrete has been performed experimentally and over a 10 Hz to 10MHz range of frequencies through alternating current (AC) impedance spectroscopy.
