Clay Minerals as Natural Nanosheets
Particles with nanometer dimensions (nanoparticles) are all around us. The finest particles of sand are blown by the wind over thousands of kilometers. The finest particles of soils are either eroded by the wind in extremely dry conditions or by water under wet conditions and deposited hundreds of kilometers or more from the origin. The air contains nanoparticles of carbon, ice, and oxides and ...
متن کاملHands on virtual clay
Simulated through a 3D grid storing the density of clay in each cell (0 for an empty cell, and 1 for a full cell). The surface is defined as the iso-surface at 0.5 of clay density. Clay behavior is captured by a layered model ensuring 3 properties: Large scale deformations (fig.1) Mass conservation by pouring the excess of matter in neighbouring cells (fig.2) Surface tension for preventing the ...
متن کاملClay Mineral Liner System for Leachates Containing Organic Contaminants
A conventional liner with a good performance against inorganic contaminants with a minimal hydraulic conductivity does not usually perform well for retention/removal of leachates containing organic contaminants. Organic modification of clay can render the naturally organophobic clay to be organophilic. Incorporation of modified organo clay along with unmodified inorganic clay in liner systems c...
متن کاملRole of clay microstructure in expandable buffer clay
Smectite-rich clay is a major engineered barrier (buffer) in repositories for heat-producing highly radioactive waste. It has the form of densely compacted blocks of clay granules and is only partly water saturated from start. The initial porewater is redistributed by the thermal gradient acting in the buffer and additional water is taken up to give ultimately complete saturation. The compactio...
متن کاملMechanical interaction between swelling compacted clay and fractured rock, and the leaching of clay colloids
We consider the interaction between a saturated clay buffer layer and a fractured crystalline rock engineered disturbed zone. Once saturated, the clay extrudes into the available rock fractures, behaving as a compressible nonNewtonian fluid. We discuss the modelling implications of published experiments carried out in Sweden and more recently in Japan. Extrusion is halted either when the advanc...
