Characterisation of pore fluid salinity dependent evaporative dewatering of kaolin using dielectric spectroscopy

摘要: Abstract Realising the importance of pore fluid salinity on dewatering behaviour fine-grained porous systems, present study systematically investigated such impacts temporal moisture dynamics kaolin subjected to evaporative dewatering. A detailed discussion is provided pertaining background processes dictating response and corresponding alterations in dielectric kaolin. Frequency dependent spectra soil, which can be considered as fingerprint transient changes condition water phase within system soil associated densification, are monitored real time during using an open-ended coaxial probe with a vector network analyser. The spatial sensitivity has been quantified through layered media approach. Combining results volume change material along its loss response, characterised hydro-mechanical from windows frequency spectroscopy.
