the steam transmission affects the both chemical and geotechnical properties of soils with various chemical compositions, so the present study intended to examine steam transmission quantity in three clay soils (non-dispersive and dispersive) in unsaturated conditions and under influence of osmotic pressure...

Attapulgite and bentonite are a kind of special clay minerals, they have some similarities in chemical composition and some material properties. Attapulgite and bentonite have strong water absorption and moisture absorption properties, and can quickly absorb the surrounding water, forming a colloidal ...
Physicochemical propertiesSoil consolidationSoil mechanicsThe mechanical behavior of compressible clay soils may be strongly influenced by physicochemical effects when concentrated pore fluids are introduced to the soil. Conceptual models have been used to explain the influence of pore fluid chemistry on the...
Clay swelling, an important phenomenon in natural systems, can dramatically affect the properties of soils and sediments. Of particular interest in low-salinity, saturated systems are osmotic hydrates, forms of smectite in which the layer separation greatly exceeds the thickness of a single smectite ...
Casagrande observed that, for all soils tested, the electro-osmotic permeability ke had an average value of 5×10−5 cm2 /Vs, with values ranging from 2×10−5 to 12×10−5 cm2/Vs for highly colloidal bentonite clay, depending on water content of the clay suspensions. Overbeek [11...

Due to their mechanical and hydraulic properties, clays are not easy to work with. Consequently, laboratory devices have to deal with various complications. A new design for an experimental set-up is proposed. Contrary to earlier devices, the clay sample is mounted in a flexible wall permeameter...
