strength and defonnation properties of all types of soils and aggregates, i.e., the higher the dielectric value, the lower the bearing capacity. Mitchell (1992) documents the idea of this relationship as he writes "As the strength of a soil depends in part on interparticle attractions, it would be expected that the strength would also be influenced by dielectric constant."

The dielectric properties of nine rock samples [limestone (8) and sandstone (4)] collected from Ewekoro in Ogun State, Nigeria were studied in the range 10 kHz – 110 MHz under ambient atmospheric conditions. It is found that dielectric constant ( e ¢ ) values of the dry samples decreases with increase in frequency in the range of r measurement.

197411· Tensile strength of limestone vs. surface tension of liquids, to strong adsorption of the liquid on a polar solid par- ticle; the cohesion between particles in the presence of such a liquid is weakened. As the dielectric constant of the liquid increases, the cohesion (and hence strength) between the particles of the solid decreases.

The relative permittivity (in older texts, dielectric constant) is the permittivity of a material expressed as a ratio with the electric permittivity of a vacuum. A dielectric is an insulating material, and the dielectric constant of an insulator measures the ability of the insulator to store electric energy in an electrical field.
