A large-scale laboratory investigation into the movement of gas and water through clay barriers exposed to the environment
This report describes a large-scale laboratory investigation into the movements of gas and water through clay barriers exposed to the environment. The test beds, each 3 m2, were constructed and filled with clay to a depth of 400 mm after compaction. One test bed contained London clay, the other glacial till. The clays were subjected to accelerated environmental cycling, and tests were carried out on samples of the clays at appropriate intervals. The tests included measurements of the mechanical, physical and chemical properties of the clays and their permeability to gas and water. Gas permeability emerged as the more appropriate for the clays being investigated. The report discusses the difficulties of measuring the permeability of partially saturated clays and the need to define the measuring techniques when specifying limiting acceptability values.
