Abstract

Efforts were made in this study to develop a methodology for estimating the dielectric constant of the fine- and coarse-grained soils, based on their dielectric dispersion. A generalized relationship that can be employed for estimating the dielectric constant of any type of soil, corresponding to a given ac frequency and any compaction state, has been developed. The utility and efficiency of this relationship has been demonstrated based on the results reported in the literature for different types of soils and glass-beads.

Keywords:
impedance spectroscopy, dielectric dispersion, fine-grained soils, coarse-grained soils, glass-beads
