Analysis of dielectric relaxation data in water-saturated sands and clays

The measurements of the imaginary part of the complex susceptibility in water-saturated sands and clays have been conducted. To explain the experimental data obtained the fractal model of medium has been used [Laboratory Humidity Ovens (Non-injection Type), BS (1964) 3718; Fleches du temps et geometric fractale, Paris Hermes, 1998]. In the range of humidity not exceeding 12%, the main contribution to the dipole relaxation is provided has bound water [A Wetting Ability Clays and Clay Minerals, Kiev, 1961, p. 292], that is reflected in the power-law exponent behavior. © 2002 Elsevier Science B.V.
