In Iran, a large extent of the soils and water are facing with salinity; so the geotechnical properties of arid and saline soils are important for engineering design. In this study, the effects of salinity on geotechnical properties of fine-grained and coarse-grained soils containing fibrous clay minerals have been studied. The results showed that salinity was mostly a flocculated agent in fine...
