Abstract

Varying weight percentages of an Ottawa sand, benzyltriethylammonium-bentonite (BTEA-clay), Wyoming bentonite (Na-clay), and water were mixed uniformly and compacted to simulate sand-and-clay liners for waste-disposal facilities. The hydraulic conductivities of the compacted soil cores were measured in triplicate. The hydraulic conductivities of cores containing 92 percent sand and 8 percent BTEA-clay were about of 10-4 cm/s. The hydraulic conductivities of cores containing 92 percent sand and 8 percent Na-clay and of cores containing 88 percent sand, 8 percent Na-clay, and 4 percent BTEA-clay were about 10-8 cm/s.
