The chemistry of the pore fluid can significantly influence the hydro-mechanical properties of soils. This is particularly true for soils containing clay minerals. Shear strength, porosity, hydraulic conductivity, stiffness and other characteristics can differ depending on whether pure water, saline solutions, acid solutions or organic substances are permeating the pore space. As a preliminary analysis, this study seeks to evaluate the effect of pore fluid salinity and pH on the index properties of a variety of natural clayey soils and artificial mixtures. The results will be validated against published results from the literature and will be used to empirically predict various mechanical properties.
