Abstract
"A cement bentonite and soil slurry wall was installed through a river levee to prevent horizontal seepage during high river levels. The maximum allowable hydraulic conductivity of the backfill was 1.0 x 10-6 cm/s at 28 days of curing. Two types of samples were taken and tested for hydraulic conductivity. Bulk samples of the backfill were cast prior to hardening and undisturbed samples were taken from the trench after the backfill had hardened.
The bulk samples typically had a hydraulic conductivity of 5.0 x 10-7 cm/s or lower while the undisturbed samples displayed a hydraulic conductivity which was greater than 1.0 x 10-6 cm/s.
The influence of curing conditions and sampling disturbance on the hydraulic conductivity was examined in this study. Several large specimens were cast using a backfill soil mix similar to the backfill used on the project. The specimens were sampled using standard Shelby tubes. The hydraulic conductivity of the tube samples were compared to 3 in. (7.6 cm.) diameter by 6 in. (15.2 cm.) tall cast samples. The tests indicated that the curing environment had little effect on the hydraulic conductivity and that sampling disturbance was the primary cause for the difference in hydraulic conductivity between the undisturbed and cast samples"--Abstract, page iii.
