Geosynthetic clay liners (GCLs) are often used as anti-seepage systems in landfills and at the bottom of tailing ponds. The performance GCL will change under different temperatures. In this study, bentonite was mixed with test solutions temperatures to measure basic indexes components analyze permeability. composition micro-structure were analyzed by X-ray diffraction, fluorescence spectrum, SE...

Landfills of hazardous waste like radioactive rest products with low activity, or ashes from incinerated organic waste, need to have top clay liners for minimizing penetration and percolation of precipitated rain and meltwater. Temperature and dry weather vary interchangeably with wet periods making the clay desiccate and fissure, and subsequently wetted etc. Top liners are commonly made of sme...

Composite liners with a geomembrane and either a compacted clay or a geosynthetic clay liner are widely used to minimize leakage from landfills and other containment systems such as leachate lagoons. While much work has been done to quantify the rates of leakage, few papers assess the impact of this leakage on groundwater quality. This is particularly important for organic contaminants because ...

Compacted clay liners (CCLs) are the main materials used in waste disposal landfills due to their low permeability. In this study, the effect on the shear resistant of clays with inorganic salt solutions as permeate fluid was experimentally investigated. For this purpose, NaCl inorganic salt solution at concentrations of 2, 5, 10% and deionized water were used. Laboratory direct shear and Vane ...
