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 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...
متن کاملAdvances and Remaining Challenges for Geosynthetics in Geoenvironmental Engineering Applications
Nine issues of importance to the use of geomembranes (GMs) and geosynthetic clay liners (GCLs) as part of composite liners in geoenvironmental applications are examined. These issues include the effect of: GCL-leachate compatibility on hydraulic conductivity; freeze-thaw on GCL performance; internal erosion on GCL hydraulic conductivity; temperature on advection and diffusion as well as desicca...
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 کاملImpact of High Concentration Solutions on Hydraulic Properties of Geosynthetic Clay Liner Materials
This study focuses on the impact of landfill high concentration solutions erosion on geosynthetic clay liner (GCL) materials permeability. The permeation tests on the GCL, submerged using different kinds of solutions with different concentrations, were carried out systematically by taking these chemical solutions as permeant liquids. Based on seasonal variations of ion concentrations in Chenjia...
