Abstract

Bentonite-sand mixtures are the essential materials for designing any types of waste disposal facilities. We must evaluate the coefficient of permeability and swelling characteristics of bentonite-sand mixtures to construct that facility. A series of various laboratory tests were performed to investigate the coefficient of permeability by direct and indirect test methods derived from consolidation theory using variable liquid limit of bentonite and bentonite-sand mixture. The coefficient of permeability varied among the direct and indirect test methods at the same void ratio. Swelling characteristics and speed were dependent on initial dry density, content of bentonite and static load.
