  • Low frequency dielectric properties of selected moist clays
    Kramer Stajnko, Janja ...
    Recently the dielectric spectroscopy studies of clay soils has been extensively used for characterization of water content in these materials in order to better understand its electrical and ... mechanical properties. In this work we have performed the low frequency (100 Hz - 100 MHz) dielectric spectroscopy of selected kaolinitic clays at different water content raging from dry, over plastic to liquid limit. Specifically, the possible correlation between the dielectric properties of the chosen samples within the moisture regime where their mechanical shear modulus has been shown to exhibit a variation in magnitude has been investigated, however the results are found to be inconclusive. For all samples investigated, depending on the moisture content, the measured capacitance response reflects the anomalous behavior within the certain frequency region where the negative values of capacitance have been observed. Here we present a novel model based on the ions random drift in the presence of an absorbing barrier explaining the observed anomalies.
