Abstract:

Slurry walls are designed to control subsurface movement of contaminants from hazardous waste site. The objective of this study was to assess the performance of some slurry wall materials. The marsh slurry viscosity and slump test were used to determine the mixed proportion of the slurry wall. The hydraulic conductivity test was used to evaluate the restricted contamination ability of the slurry walls. In this research, the soil-bentonite wall (SB), soil-cement-bentonite wall (SCB) and soil-bentonite wall with additives (natural humus, zeolite or activated carbon) mixtures permeated with distill water; 2% and 6% sulphuric acid, landfill leachate and diesel oil. The experiment results showed that: (1) the hydraulic conductivity of the SB wall specimens increased with permeation of sulphuric acid, landfill leachate, diesel oil compared with the permeated fluid (distill water); (2) the hydraulic conductivity of the SCB wall specimens were larger than the soil-bentonite wall when the permeated fluid was distilled water whereas when the permeated fluid changed from distilled water to landfill leachate or diesel oil, the permeability of the SCB wall specimens presented a slight decrease; (3) for other additives (natural humus, zeolite or activated carbon) addition to the SB wall specimens, the hydraulic conductivity of these additives specimens did not fluctuate obviously when the permeated fluid transformed from distilled water to above contaminants. All the hydraulic conductivity of the slurry wall specimens met the permeability standard of the USEPA .
