Permeability of soil plays an important role in geotechnical engineering and is commonly determined by methods combining measurements with theory. Using the double-scale asymptotic expansion method, the Navier-Stokes equation is numerically solved to calculate the permeability, based on the homogenization method and the assumption that the homogeneous microstructure of the relevant …
Tests were also conducted using the conventional flexible wall permeameter on samples that were trimmed horizontally, so as to measure the hydraulic conductivity in the horizontal directions for ...

Considering the calculation of permeability for kaolin clay as an example, the calculated permeability was m 2 at the largest void ratio, while the measured permeability m 2; also, the calculated value was m 2 when the smallest void ratio was determined to be, while the measured value m 2.
Jul 17, 2017· The writers wish to present some additional data obtained independently and with different techniques that confirm the results published in the paper. For these tests, the speswhite kaolin clay was prepared as a slurry with a water content of 133 percent and was then consolidated one-dimensionally under an axial stress of 100 kPa in a 203 mm dia. tube.
Grain size distributions for the Loire sand, the kaolin used for the erosion test, and the bentonite used for the permeability measurements The repeatability of the production is guaranteed by the following procedure: – First, the sand is mixed (145rpm) during three minutes with a water content of 8%.
Metakaolin is the anhydrous calcined form of the clay mineral kaolinite.Minerals that are rich in kaolinite are known as china clay or kaolin, traditionally used in the manufacture of porcelain.The particle size of metakaolin is smaller than cement particles, but not as fine as silica fume
This thesis is concerned with an investigation into some aspects of the permeability measurement and permeability characteristics of reconstituted saturated supreme kaolin clay. Development of permeability anisotropy is investigated when the sample has experienced: (1) anisotropic consolidation, and (2) undrained shear.
Somogyi (1979) defined the permeability changes during a one-dimensional compression of a soil using Equation (9), where k (m/s) is the hydraulic conductivity, e is the void ratio, and C (m/s) and ...

ABSTRACT: A variety of clay specimens (Kaolin, Belfast Upper Boulder Clay and Belfast Sleech) were subjected to British Standards Triaxial Permeability Tests and Accelerated Permeability Tests in order to examine how the permeability predicted (under uniform effective stresses and conditions) varied depending on the testing method adopted.
some measurements of the permeability of kaolin This paper reports an experimental investigation of the vertical and horizontal permeabilities of speswhite kaolin clay. The permeabilities were measured using falling head permeability tests.
blems to be solved. The permeability of such soils is determinable by means of held pumping tests or by laboratory measurements. It is also computed by means of for-mulas by HAZKN (2), JAKY (3), and TKRZAGHI ("), on the basis of the particle size distribution curves of soil samples obtained from sample borings.

The author of this Thesis did some improvements in the permeability device, its characterisation, all the measurements and their analyses, and their reporting (this manuscript). The author also analysed the results of the fluid flow simulations (has thus produced, e.g., Figs. 8, 9, 11 and 12)

Some of the OnePetro partner societies have developed subject- specific wikis that may help.
In this paper, the authors propose some simple expressions, based on pedologic properties, to estimate the value of k. Using experimental results of their own and taken from the literature, it is shown that the proposed pedotransfer functions can be used for quickly estimating the k value for granular and plastic/cohesive soils.
Direct measurements of the flow characteristics of the mixtures show that a simple relationship can be obtained between permeability of the mixture and the volumetric packing of the clay matrix, for clay contents down to 40%. ...

Soil permeability is the property of the soil to transmit water and air and is one of the most important qualities to consider for fish culture. A pond built in impermeable soil will lose little water through seepage. The more permeable the soil, the greater the seepage. Some soil is so permeable ...
trolling the permeability of kaolinite was the degree of dispersion of the kaolinite in the original sus- pending fluid. They also concluded (see also Michaels and Lin, 1955) that electroosmotic counterflow might be of some importance when aqueous solutions were used as the permeants but
