Klein, K. and Santamarina, J. C. (1996). "Discussion to the paper by J.Q. Shang, K.Y. Lo, and I.I. Inculet, on the Polarization and Conduction of Clay-Water-Electrolyte Systems." ASCE Journal of Geotechnical Engineering, Vol. 122, No. 11, pp. 954-955
The authors measured the permittivity of two natural Leda clays (undisturbed and remoulded samples) at a frequency of 60 Hz in a capacitor-type cell. Low frequency permittivity measurements of clay-water-electrolyte systems are difficult to obtain using capacitor-type cells due to electrode polarization. This phenomenon and its implications are discussed next.
