Abstract
In recent years the use of cutoff or slurry walls has increased in the containment of hazardous waste. Several materials have been utilized for backfill in slurry walls. Two important properties of the material are shear strength and permeability. Previously, sodium bentonite had been used. However, it was discovered that variable pH would cause an increase in permeability. Studies have shown calcium bentonite have a constant permeability with varied pH (Oweis and Khera, 1990). This study was undertaken to determine strength of calcium bentonite as affected by cement and slag.
Triaxial shear tests and unconfined compression tests were done on different mixes of cement bentonite specimens. The addition of slag increases the strength of the mixture. Cement bentonite specimen with slag cement ratio of 2:1 gave the highest strength.
