Calcium and Sodium Bentonite for Hydraulic Containment Applications

Journal of Geotechnical and Geoenvironmental Engineering, 1997
The hydraulic conductivity of calcium and sodium bentonites was investigated for sand-bentonite mixtures, a thin bentonite layer simulating a geosynthetic clay liner (GCL), and bentonite-cement mixtures simulating backfill for a vertical cutoff wall. The permeant liquids were tap water and distilled water containing 0.25 M calcium chloride. In general,

Permeability and expansibility of sodium bentonite in dilute solutions

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2010
In developing the dynamic force balance model for colloidal expansion, it was acknowledged that accurate description of the viscous drag force, or equivalently the permeability, is very important t ...

Modified bentonite (Sodium Smectite) sealant membrane

Engineering Geology, 1985
Abstract A smectite-coated polypropylene membrane has strength, ease of placement and inspection, plus strong resistance to leakage of hazardous waste liquids or slurries. Natural smectite must be modified by chemical additives to develop resistance to contamination.

Diffusion of anions and cations in compacted sodium bentonite: Dissertation

1994
This thesis presents the results of studies on the diffusion mechanisms of anions and cations in compacted sodium bentonite, which is planned to be used as a buffer material in nuclear waste disposal in Finland. The diffusivities and sorption factors were determined by tracer experiments.
