Dielectric dispersion method for non-destructive quantification of soil composition



Dielectric dispersion method for non-destructive quantification of soil composition



Geotechnical Special Publication 110(Pages 1-34



The Maxwell-Wagner-Fricke theory for electrical conduction through heterogeneous media has been extended to develop a theoretical relationship for fluid-saturated porous media, accounting for particle orientation, porosity and the dielectric constants of the pore fluid, solid phase and mixture. This theory is further extended to account for the dielectric dispersion behavior of clay-water-electrolyte systems by considering the surface conductance of particles. The variation of the dielectric constant, epsilon , and the conductivity, sigma , as a function of frequency is the electrical dispersion behavior. The magnitude of the variation of epsilon over the radio frequency range (1-100 MHz) is referred to as Delta epsilon (sub 0) . Dielectric dispersion behavior is shown to be controlled by the mineral-solution interface characteristics as influenced by mineralogy and the pore fluid composition. Delta epsilon (sub 0) is shown to be related to swell potential and compression index. The electrical dispersion method presented, provides a rapid non-destructive method of quantifying the composition of soils.
