A Study of Membrane-Permeant Compatibility



Triaxial cells are often used to conduct permeability tests on soil specimens. The specimen inside a flexible membrane, is placed in the triaxial cell. The permeant is then percolated through the specimen, and the hydraulic conductivity is measured. However, the incompatibility of the available latex membranes to some permeants is a major drawback for this procedure. In some cases the membrane experiences excessive deformations resulting in wrinkles and inaccurate measurements caused by possible side leakages. This paper describes a test procedure and testing equipment that can readily be used to predict the membrane-permeant compatibility. Test results for different membranes and various organic fluids are also provided.
