Hydraulic conductivity and moisture/density relationships of candidate packing material
Laboratory experiments have been completed to provide moisture/density relationship and hydraulic conductivity physical property data for packing materials. Both moisture/density relationship and hydraulic conductivity tests were performed using packing materials consisting of bentonite clay and crushed basalt rock. Moisture/density relationship tests were performed on 20:80, 25:75, 50:50, 75:25, and 100:0 (wt.%) bentonite/basalt samples using the modified protor test. A set of moisture content versus dry density curves were generated. A typical trend of higher achievable dry density at higher basalt content was indicated due to the difference in specific gravity of basalt and bentonite. Hydraulic conductivity tests were run on 25:75 (wt.%) bentonite/basalt samples over a density range of 1.45 to 2.03 g/cm{sup 3}. Test results indicate a decrease of hydraulic conductivity as a function of both temperature and hydraulic gradient. The data gathered are applicable to both Engineered Barriers and Repository Seals Development. 9 refs., 22 figs., 11 tabs.
