... of permittivity and electrical conductivity as a function of water content, ionic concentration and clay mineralogy. It was found that swelling clay shows a wide variation in real and imaginary permittivity as a function of water content at low ionic concentration. In addition, the variation of permittivity...

...Yongjoon Choe; Hangseok Choi; Jongmuk Won Internal erosion by suffusion within a sand–clay mixture may occur as detachment of clay particles, which is induced by a decrease in ionic concentration (IC) along with application of a high hydraulic gradient. Through designed laboratory soil-column...
