Clays are used as barriers for the isolation of landfills and contaminated sites. They are envisioned as long-term storage media for hazardous materials and radioactive wastes, and as seals in the case of geological CO2 sequestration or energy storage. Clay properties greatly influence the integrity, efficiency, and safety of these applications. Natural and Engineered Clay Barriers provides a clear view of the fundamental properties of clay materials and how these properties affect their engineering applications. This volume focuses on how the mass transfer properties (hydraulic permeability, gas fluxes, molecular diffusion, semi-permeable membrane properties), geochemical reactivity (adsorption, dissolution) and mechanical properties of clay barriers at the macroscale are influenced by phenomena that occur at clay mineral - water interfaces. Examines clay properties from the molecular to the macroscopic scale Addresses experimental and modeling issues Authored by experts in the properties of clay barriers

This Special Publication contains 43 scientific studies presented at the 5th conference on ‘Clays in natural and engineered barriers for radioactive waste confinement’ held in Montpellier, France in 2012. The conference and this resulting volume cover all the aspects of clay characterization and behaviour considered at various temporal and spatial scales relevant to the confinement of radionuclides in clay, from basic phenomenological process descriptions to the global understanding of performance and safety at repository and geological scales. Special emphasis has been given to the modelling of processes occurring at the mineralogical level within the clay barriers. The papers in this Special Publication consider research into argillaceous media under the following topic areas: large-scale geological characterization; clay-based concept/large-scale experiments; hydrodynamical modelling; geochemistry; geomechanics; mass transfer/gas transfer; mass transfer mechanisms. The collection of different topics presented in this Special Publication demonstrates the diversity of geological repository research.

The use of clay barriers for waste-isolating purposes has gained increasing attention in the geotechnical engineering community. Practical interest is linked to fundamental research, which includes examination of the behaviour of compacted materials and expansive clays. The interaction between the barrier, waste and the surrounding ground may involve several thermo-hydro-mechanical and chemical-coupled processes that have been analyzed by means of 'in situ' tests, laboratory experiments and numerical modelling. Large-scale field tests have been developed in recent years by European Agencies dealing with the management of radioactive waste. These experiments have provided an opportunity to calibrate and to validate research models and offer benefits in terms of experience of instrumentation and installation techniques. The book includes about sixty papers presented in a symposium held in Spain in 2003. The four main topics of the book are: field emplacement and instrumentation techniques; fundamental research, material behaviour (i.e. bentonite), and laboratory testing; barrier behaviour and THM modelling; and chemical effects, HC and THMC modelling.

It is internationally accepted that the safest and most sustainable option for managing radioactive waste is geological disposal, utilizing both engineering and geology to isolate the waste and contain the radioactivity. This Special Publication contains 25 scientific studies presented at the 6th conference on ‘Clays in natural and engineered barriers for radioactive waste confinement’ held in Brussels, Belgium in 2015. The conference and this resulting volume cover many of the aspects of clay characterization and behaviour considered at various temporal and spatial scales relevant to the confinement of radionuclides in clay, from basic phenomenological process descriptions to the global understanding of performance and safety at repository and geological scales. The papers in this volume consider research into argillaceous media under the following topic areas: large-scale geological characterization; general strategy for clay-based disposal systems; geomechanics; mass transfer; bentonite evolution and gas transfer. The collection of different topics presented in this Special Publication demonstrates the diversity of geological repository research.

In the seven years since the publication of the first edition of Sustainable Practices in Geoenvironmental Engineering, the combination of population growth and increased exploitation of renewable and non-renewable natural resources has added increased stresses on the quality and health of the geoenvironment. This is especially true when viewed in the context of the growing demand for food and shelter, energy and mineral resources, and their resultant effects on the natural capital of the geoenvironment. Completely revised and updated, this second edition of a bestseller introduces and discusses the concept of "stressors" and their impacts on the geoenvironment. See What’s New in the Second Edition: Clear definition of the geoenvironment New tools and remediation technologies, new management methods for geohazards, and enhanced coverage of social and economic sustainability Innovative approaches and techniques for reaching geoenvironmental sustainability More detail on treatment technologies, both in situ and ex situ Discussion on the mitigation of geodisasters Additional sections to discuss sustainability assessment protocols Updated information on models for prediction of contaminant behavior The authors explore the technologies that take into account targets, exposure routes (if applicable), future land use, acceptable risks, legislation, and resultant emissions/discharges in establishing the criteria and tools for evaluating technologies and protocols for environmental management of the impacted land. They then discuss how to choose the correct ones to use in different situations to protect the quality and health of natural resource and capital of the geoenvironment and ensure that these geoenvironmental natural resources and capital remain available for future generations and to develop innovative and sustainable techniques to make land more stable and safer.

One of the principal objections to or problems with the use of nuclear fuel is that a proven method for safe disposal of spent nuclear fuel has yet to be established. The central focus of most schemes underway to dispose of these high-level radioactive wastes relies on clay-based buffers and barriers to isolate spent fuel canisters in boreholes deep underground in specially constructed tunnels and caverns. Current thought on the principal methods of containment of high-level radioactive wastes is presented in this book. The authors proceed to discuss the processes and mechanisms involved in the development of long term properties and performance of clay-based buffers and backfills. The procedures and methodologies used to undertake predictions and performance assessments of these materials are also examined. This is an invaluable reference for professionals, researchers, academics and regulators engaged in the development of radioactive waste sites.

Certain wastes such as nuclear wastes, are so hazardous that their disposal creates a major challenge requiring considerable technical skill and understanding. Their effective isolation in the ground depends on the properties of the surrounding clays. This authoritative book explains the detailed function of clay-based engineered barriers, gives a number of examples of the design and construction of successful sites, and sets out conceptual and theoretical models for the prediction of their performance. It begins by providing a scientific grounding in the relevant aspects of clay science and successively moves onto the practicalities, while retaining the scientific slant. It will be useful for students, and invaluable for research institutes, specialists in environmental protection agencies and consultants in the field of disposal of hazardous waste.
