Dec 02, 2006· The characterisation of flow through porous media is important for all solid–liquid separation and fluid transport realms. The permeability of porous media can be anisotropic and furthermore, the extent of anisotropy can be increased as a result of an applied compressive force. However, the understanding of how anisotropy develops is incomplete. An overview of research on permeability ...

Hydraulic anisotropy of homogeneous soils and rocks ...

Apr 01, 1989· Many values of the ratio kmax/kmin are available for clays and rocks which can be cut for tests in different directions. In comparison, few reliable results are available for non-cohesive materials. The hydraulic anisotropy ratios of homogeneous clays, rocks and granular soils appear to be very similar. In particular, kmax/kmin seems to be lower than 4, which confirms that this ratio has an ...

Determination of permeability of sandy clay by triaxial test

Brief comparisons would be made between other laboratory methods and the Triaxial test, eventually justifying why the latter was the preferred method for permeability measurements of sandy clay. In the process, possible permeability trends would also be identified, by varying the percentage of clay (Kaolin) in a sand-clay mixture.

Velvacast Kaolin - Digitalfire

Notes. A large particle size kaolin intended for casting slips. It is low in plasticity and fires a darker color than what the reported iron would indicate? Combining some of this material with other kaolins of finer particle size in casting recipes will reduce casting times because of the greater permeability of the slip. Kaolins of this type are also valuable for use in tuning the shrinkage ...
