...V. Khan; S. Rajesh Geosynthetic clay liner (GCL) is commonly used in cover system of engineered landfill to limit migration of gases and infiltration of water. In engineered landfill, gas transfer occurs by advection and diffusion, which may take place at different time frames or simultaneously...

..., it is beneficial. In contrast, cryogenic suction arising with open system freeze–thaw cycles is shown to result in the formation of ice lenses both within the geosynthetic clay liner (GCL) and at the GCL geomembrane interface. Although limited, the data suggest that the effect of ice lens formation on interface...

...A. G. Pillai; M. L. Gali Inadequate shear strength mobilization at the interfaces results in translational failures in Geosynthetic Clay Liners (GCL). Periodic addition of solid waste into the landfill causes additional normal and shear stresses in GCLs. The mechanical response of GCLs and fibre...

...S. Rajesh; A. Jain Geosynthetic clay liners (GCLs) are used in landfill applications because of their high deformation resistance and excellent self-healing ability. In the present study, air and hydraulic flow characteristics of natural bentonite based GCL (GCL-N) and polymer amended bentonite...

...R. K. Rowe; S. Hamdan Two geosynthetic clay liners (GCLs) with sodium bentonite and three GCLs with polymer-amended bentonite were subjected to wet–dry cycles selected to simulate the conditions to which a GCL on an 18° slope might be subjected: for a GCL below an exposed geomembrane wrinkle...

... on the transport of GONPs in the geosynthetic clay liner (GCL). The experimental results show that pressure affected the mobility of GONPs at high input concentrations, while this effect was smaller at low input concentrations. The retention of GONPs in a GCL containing thermally modified bentonite (TMB...

...T. Özdamar Kul; A. H. Ören The hydration performance of two geosynthetic clay liners (GCLs) over compacted zeolite is investigated in this paper. Zeolite was chosen as the subsoil because of its greater optimum water content with respect to other natural soils (41%). The water content changes...

...J. Scalia, IV; G. L. Bohnhoff; C. D. Shackelford; C. H. Benson; K. M. Sample-Lord; M. A. Malusis; W. J. Likos The sensitivity of sodium bentonite (Na-B) to adverse chemical interactions has spurred development of enhanced bentonites (EBs) for geosynthetic clay liners (GCLs) that provide superior...

...C. A. Bareither; M. Soleimanian; S. Ghazizadeh The objective of this study was to develop, verify, and assess a direct shear apparatus to measure the internal shear strength of geosynthetic clay liners (GCLs) when exposed to elevated temperature and non-standard hydration solutions. Shear boxes...

...A. Bouazza; M. A. Ali; W. P. Gates; R. K. Rowe The hydration of a needle-punched, thermally treated and powdered bentonite-based geosynthetic clay liner (GCL) from four different subsoils was studied at optimum moisture content +2% under isothermal conditions. Contrary to the belief that GCL...

...A. K. Rentz; W. A. Take; R. W. I. Brachman; R. K. Rowe The surface temperature of an exposed composite liner consisting of a geosynthetic clay liner (GCL) covered by a black geomembrane (GMB) can routinely exceed 60°C during summer solar exposure before falling to ambient air temperature at night...

...J.L. Hanson; T.S. Chrysovergis; N. Yesiller; D.C. Manheim ABSTRACT: This investigation was conducted to determine the effects of temperature and moisture on the shear strength of a double nonwoven geosynthetic clay liner (GCL) and a high-density polyethylene textured geomembrane (T-GM) interface...

...P.J. Fox; T.D. Stark ABSTRACT: This paper presents an invited update to our 2004 state-of-the-art report and provides a comprehensive source of information on the shear strength and shear strength testing of geosynthetic clay liners (GCLs). Essential concepts of shear stress–displacement behavior...

...G. Di Emidio; F. Mazzieri; R.-D. Verastegui-Flores; W. Van Impe; A. Bezuijen ABSTRACT: The purpose of hydraulic barriers, such as geosynthetic clay liners (GCLs), is to isolate waste liquids from the environment. Bentonite clay is widely used in GCLs because of its elevated sealing capacity...

...M.S. Hosney; R.K. Rowe ABSTRACT: The performance of geosynthetic clay liners (GCLs) above arsenic-rich gold mine tailings was investigated by the construction of a test cover comprised of three GCL products placed above the tailings at an abandoned gold mine in Nova Scotia, Canada. In parallel...
