Abstract: Knowledge on the impact of pore-fluid salinity, characterized by the changes of pH, ionic concentration, material composition, and other factors, on geotechnical engineering applications involving hydro-chemo-mechanical systems, is expanding. These systems range from conventional geotechnical applications to geo-environmental facilities. A favorable soil of bentonite was often adopted as an admixture in these projects owing to its high swelling and self-sealing capabilities. Among a list of parameters, hydraulic conductivity and undrained shear strength are the most fundamental ones that are closely related to the engineering performance of sealing materials. The characterization of these two parameters for soil-bentonite mixtures, while taking into account the influence of pore-fluid salinity, is therefore a matter of concern at both academic and practical levels.
