Hydraulic Conductivity of Geosynthetic Clay Liners to Low-Level Radioactive Waste Leachate
Hydraulic conductivity was evaluated for eight commercially available geosynthetic clay liners (GCLs) permeated with leachate characteristic of low-level radioactive waste (LLW) disposal facilities operated by the U.S. Department of Energy (DOE). Two of the GCLs (CS and GS) contained conventional sodium bentonite (Na-B). The others contained a bentonite–polymer mixture (CPL, CPH, GPL1, GPL2, an...
متن کاملPermeability of Natural Clay Liners: Effect of Accelerated Permeability Testing on Soil Structure
A variety of clay specimens (Kaolin, Belfast Upper Boulder Clay and Belfast Sleech) were subjected to British Standards Triaxial Permeability Tests and Accelerated Permeability Tests in order to examine how the permeability predicted (under uniform effective stresses and conditions) varied depending on the testing method adopted. The specimens were then freeze-dried to preserve their post-test ...
متن کاملapplication of modified clays in geosynthetic clay liners for containment of petroleum contaminated sites
in this research, hydraulic and sorption behavior of geosynthetic clay liners (gcls) withordinary and modified clay exposed to crude oil were studied. both modified and ordinary bentonites wereinvestigated to evaluate crude oil adsorption efficiency on the liners. because soil permeability exposed tocrude oil is a major parameter in measuring the contaminants migration in soils, the permeabilit...
متن کاملFactors affecting hydration of Geosynthetic Clay Liners in landfill applications Facteurs influençant l’hydratation des géosynthétiques bentonitiques dans les applications d'enfouissement
The progression of hydration of Geosynthetic Clay liner (GCL) from underlying subsoil was studied for three GCL products under simulated landfill conditions, before and after being covered by municipal solid waste. GCL hydration is shown to be highly dependent on the GCL manufacturing techniques, the grain size distribution and initial moisture content of the subsoil. The hydration behaviour of...
متن کاملComparison Of Hydraulic Conductivity Test Methods for Landfill Clay Liners
Accurately measuring the in situ hydraulic conductivity (permeability) of a clay liner is a major factor in the construction of landfill containment systems. Laboratory and large-scale field test methods are often utilized on test pads constructed prior to placement of the production liner to determine the hydraulic conductivity of the clay. While these test methods provide reliable results, th...
