Understanding of water and mass transfer in fractured rock mass is essential to the safety
and environmental problems associated with rock engineering. It is still challenging to …

Diffusion of contaminants can play a significant if not dominant role in many applications
encountered within the field of environmental geotechnics. The objective of this paper is to …

Smectite-based geosynthetic clay liners (GCLs) are popularly employed as hydraulic
barriers due to their low permeability and high swelling capacity. The exposure of GCLs to …

A novel soil-bentonite backfill is proposed for use in vertical cutoff walls to contain phenol in
groundwater at contaminated sites. The backfill consists of sand and bentonite modified with …

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 …

The aim of this Specialized Lecture is to present the recent advances and issues, as well as
original research, on Modified Clays for Barriers. Topics of interest include:(1) long-term …

Organoclays are organic-rich clay minerals, synthesized under controlled laboratory
conditions, with engineering properties enhanced for use in containment applications …

The results of a project aimed at identifying performance-based indicators that can be used
by landfill operators to check the suitability of GCLs for bottom barrier applications are …

Sorption of four heavy metals (Pb, Cd, Zn and Hg) to calcium bentonite (Ca bentonite),
hexadecyltrimethylammonium bentonite (HDTMA bentonite) and benzyltriethylammonium …

Organoclays synthesized from single chain quaternary ammonium cations (QAC)((CH3)
3NR+) exhibit different mechanisms for the sorption of nonpolar organic compounds as the …
