APPLICATIONS OF DIELECTRIC CONSTANT MEASUREMENTS IN GEOTECHNICAL ENGINEERING

It is emphasised in this paper that the soil behaviour is governed by a complex interaction of compositional properties and environmental factors. The existing method for geotechnical investigations does not measure this interaction in a meaningful manner. It is shown that dielectric constant measurement of a clay-water-electrolyte system is a fundamental soil property that determines both the compositional and environmental influence. Based on the electrical response characteristics of soils, a new approach for geotechnical investigations is proposed. Details of the experiment and the significance of electrical measurements used are described. The proposed approach involves simple and easy to perform laboratory tests. The main objective of this paper is to show the potential use of dielectric constant measurements to characterise soils and predict their behaviour. Some applications of the approach presented include determination of cation exchange capacity and expansion index of soils, identification of dispersants and flocculants identification and the classification of stabilization. The scope for further research is discussed. (Author/TRRL)
