Permeability of clay
WebA recent study evaluated dentin permeability of specimens treated with the same paste containing arginine and calcium carbonate and showed that the permeability dropped to 40% after treatment and then increased to about 65% after cycling. 24 The difference between the data from this previous study post-treatment and post-cycling permeabilities ... WebFeb 19, 2024 · The permeability of shales is several orders of magnitude lower than that of coarser-grained rocks such as sandstone. Therefore, shales and even sandstones with a moderate amount of clay content (shaly sandstones) control the flow at which fluids move underground. Clay can reduce porosity, increase tortuosity and block the pore throats.
