·Oil sands as the third largest proven crude oil reserve in the world are defined as either loose sands or partially consolidated sandstones 1100 1500 2000 and 2500 grains Permeability was calculated using sub pore scale computational study for all 30 samples Results show the same trend as discussed above The average permeability
The permeability coefficient of cement and polymer grouted silty sand after 28 days could reach × 10⁻⁷ cm/s while the improvement of their compressive strength was relatively low with
·The permeability k of lime and cement treated clayey soils was investigated in the laboratory by flexible wall permeability tests and oedometer tests Test results indicate that for the cement treated soils with up to 8% cement content by dry weight the value of k is almost equal to that of untreated soils under identical void ratio e conditions and the k value
·The overall permeability of a soil mass is strongly influenced by its macrostructure; clays containing fissures or continuous bands of sand will have permeabilities that are many times that of the clay material itself Also since flow tends to follow the line of least resistance stratified soils often have horizontal permeabilities which are
·In order to explore the factors affecting the permeability of sandy soil Su et al [12] carried out a single particle size and different gradation sand soil permeability tests and found that the
·A series of constant head hydraulic conductivity tests were conducted to determine the permeability of Ottawa F65 sand at different densities The tests followed the ASTM D 2434 standard testing procedures Table shows the hydraulic conductivity for different initial void ratios The hydraulic conductivity values presented are corrected to

·The separate end members permeability models are combined by filling the sand pores progressively with shale and then dispersing the sand grains in shale The permeability of sand shale mixtures is shown to have a minimum at the critical shale content at which shale just fills the sand pores Pure shale has a slightly higher permeability
·The impact of closed system freeze thaw cycles on the permeability of clay till and sand bentonite mixtures was examined in a laboratory test program The bentonite content of the sand bentonite mixtures varied from to 25% Test samples were prepared by dry mixing moisture conditioning and compacting materials according to ASTM D698 method A
·Various mechanisms can affect the permeability of dense unconsolidated sands Volumetric dilation can lead to permeability increase whereas strain localization in shear bands may increase or decrease the permeability depending on the state of compaction and on the level of grains breakage inside the band To investigate these various mechanisms an experimental
