Grouting Materials for Ground Treatment: A Practitioner's Guide

On Conductivity of Soils with Preferential Flow Paths
Laboratory soil column experiments were conducted to study the distribution of preferential flow paths resulting from removal of colloidal size clay particles. These experiments specifically...

Proposed Models of Colloid-Facilitated Transport for Total-System Performance Assessment

Sorption of Radionuclides at Tracer Level on Mineral Colloids

Colloid Stability in a Proposed Nuclear Waste Repository

Detachment of Humics-Coated Colloids from Fluidized Beds

Colloid-Facilitated Transport of Hydrophobic Compounds in Sandy Soils

Assessment of Clay Colloid Transport and the Associated Transport of Herbicides in Subsurface

How Should the Migration and Retardation of Colloids be Characterized?

Colloidal Fouling of Reverse Osmosis Membranes
Experiments on the fouling of thin film composite and cellulose acetate reverse osmosis membranes by aluminum oxide colloids are reported. Fouling was significant at high ionic strengths,...

Movement of Colloids Under Hydraulic Gradients
A model was developed for analyzing the movement of colloidal clay particles in laboratory soil columns. The physical mechanisms of detachment of particles from the soil matrix, their...

Scenario Development for Performance Assessment—Some Questions for the Near-Field Modelers
In an attempt to achieve completeness and consistency, the performance-assessment analyses developed by the Yucca Mountain Project are tied to scenarios described in event trees. Development...

Geochemistry for High Level Waste: An International Comparison
This paper presents a brief summary of some of the recent and on going geochemical research related to the disposal of high level radioactive waste. For most categories of research (basic...

Modelling Colloidal Transport of Radionuclides Through Porous Media
General acknowledgement of the potential role of colloids in enhancing radionuclide transport has prompted the preliminary development of a mechanistic colloid transport model as part...

Are Colloids Important for Transport Rate Assessment of Radionuclides? A Microscopic Modeling Approach
Understanding the transport phenomena of radionuclides migrating through weakly-permeable rocks forms an essential part of far-field safety assessment studies. Colloidal matter can be...

Open Channels in Fractures Maintained by Deposition and Erosion of Colloids
Colloids initially suspended in the water in fractures can deposit onto the fracture surfaces, and will partially or fully clog the fracture. The amount of clogging will depend on whether...

Osmotic Suction as a Valid Stress State Variable in Unsaturated Soil Mechanics
The hypothesis of the research being presented is that the osmotic suction of soil pore fluid is an independent, valid stress sate variable for unsaturated soils. A review of concepts...

Quantitative Comparison Between Colloidal and Solute Transport

Characteristics of Colloids in Landfill Leachate
Leachate was collected from a municipal landfill which has been closed for about 15 years. The sample was collected (under a N2 atmosphere) only...
