Laboratory Determination of Multicomponent Effective Diffusion Coefficients for Heavy Metals in a Compacted Clay
contaminant transport diffusion coefficients heavy metals clay liner Ankara clay
2009/7/7
Diffusion and sorption of heavy-metal ions (Cd, Cr, Cu, Fe, K, Mn, Ni, Pb, and Zn) through an Ankara clay liner were studied experimentally. The Ankara clay consists of calcite, quartz, smectite and i...
Evaluation of Gas Transport Properties of Backfill Materials for Waste Disposal: H2 Migration Experiments in Compacted Fo-Ca Clay
Density Fo-Ca Clay Gas Critical and Breakthrough Pressures Gas Preferential Pathways H2 Migration Water Saturation Degree

Abstracts: Swelling clays may play a major role in the underground disposal of high-level nuclear waste (HLW) in deep geological formations. A multibarrier concept including a waste container, a steel...
Hydraulic Conductivity of Thirteen Compacted Clays
Clay liners Compacted clays Hydraulic conductivity
2011/12/28
Hydraulic conductivity tests were conducted on thirteen compacted clayey soils being used for compacted clay liners at landfills throughout the United States. The soils were prepared to various moldin...
Sorption parameters are important components of models used to predict mass transport through dense or compacted earthen materials. These parameters are, however, generally determined in batch tests w...
Surface Diffusion: Is it an Important Transport Mechanism in Compacted Clays?
Compacted clays Surface diffusion Transport mechanism
2011/12/29
Surface diffusion, or migration within the electrical double layer next to mineral surfaces, is often invoked as a significant contributor to the overall diffusion coefficient in compacted clays, part...
Swelling Components of Compacted Ca-Montmorillonite
Compaction Double layer theory Montmorillonite Pore-size distribution Swelling Water adsorption
2012/2/8
Intracrystalline water adsorption of Ca-montmorillonite was calculated as the product of one-half the interlayer spacing from X-ray powder diffraction analysis and the difference between the desorptio...
Swelling Characteristics of Compacted, Expansive Soils
Swelling Characteristics Compacted Expansive Soils
2012/2/20
The limitations of existing methods for the prediction of swelling behavior of compacted soils are examined. Both the purely theoretical approach and the purely empirical approach are found to be inad...
Microstructure and Pore Structure of Impact-Compacted Clays
Microstructure Pore Structure Impact-Compacted Clays
2012/2/20
The microstructures of impact-compacted kaolinite and illite clays, after drying, were investigated by pore size-distribution measurements, X-ray orientation determinations, and scanning electron micr...
