STRENGTH AND STIFFNESS OF UNSATURATED SAND-BENTONITE 'BUFFER'

Results are presented from a series of undrained triaxial compression tests on a dense 1:1 mixture of sand and bentonite. Tests were done with degrees of saturation from 50% to 100%, confining pressures from 0.2MPa to 1.8MPa, and temperatures from 26 degrees C to 100 degrees C. The observed stress-strain behaviour is ductile. Undrained strengths increase with confining pressure and with higher suctions resulting from lower saturations. They decrease with temperature. Normalized stiffnesses E50/Su decrease with pressure and increase slowly with saturation. (A) For the covering abstract see IRRD 881647.
