Available in PDF, EPUB and Kindle. Book excerpt: Aecl has submitted an environmental impact statement (eis) to evaluate the concept of nuclear fuel disposal at depth in crystalline rock of the canadian shield. in this disposal concept used fuel would be emplaced in corrosion-resistant containers which would be surrounded by clay-based buffer and backfill materials. once groundwater is able to penetrate the buffer and corrosion-resistant container, radionuclides could be transported from the waste form to the surrounding geosphere, and eventually to the biosphere. the release of radionuclides from the waste form and their subsequent transport would be determined by the geochemistry of the disposal vault and surrounding geosphere. organic substances affect the geochemistry of radionuclides through complexation reactions that increase solubility and alter mobility, be affecting the redox of certain radionuclides and be providing food for microbes. the purpose of this study was to determine whether the buffer and backfill materials proposed for use in a disposal vault contain organics that could be leached by groundwarer in large enough quantities to complex with radionuclides and affect their mobility within the disposal vault and surrounding geosphere. buffer material, made from a mixture of 50 wt.% avonlea sodium bentonite and 50 wt.% silica sand, was extracted with deionized water to determine the release of dissolved organic carbon, humic acid and fulvic acid. the effect of radiation and heat from the used fuel was simulated by treating samples of buffer before leaching to various amounts of heat (60 degrees c and 90 degrees c) for periods of 2,4 and 6 weeks, and to ionizing radiation with doses of 25 kgy and 50 kgy. humic substances were isolated from the leachates to determine the concentrations of humic and fulvic acids and to determine their functional group content by acid-base titrations. the results showed that groundwater could leach significant amounts of organics that would complex with radionuclides such as the actinides, affecting their solubility and transport within the disposal vault and possible the surrounding geosphere. heating and radiation affect the amount and nature of leachable organics. however, one of the key parameters that needs to be addressed is the mobility of organic molecules through an intact buffer and backfill.

Available in PDF, EPUB and Kindle. Book excerpt: Clay minerals are one of the most important groups of minerals thatdestroy permeability in sandstones. However, they also react withdrilling and completion fluids and induce fines migration duringhydrocarbon production. They are a very complex family of mineralsthat are routinely intergrown with each other, contain a wide rangeof solid solutions and form by a variety of processes under a widerange temperatures and rock and fluid compositions. In this volume, clay minerals in sandstones are reviewed interms of their mineralogy and general occurrence, their stable andradiogenic isotope geochemistry, XRD quantification, their effectson the petrophysical properties of sandstones and theirrelationships to sequence stratigraphy and palaeoclimate. Thecontrols on various clay minerals are addressed and a variety ofgeochemical issues, including the importance of mass flux, links tocarbonate mineral diagenesis and linked clay mineral diagenesis ininterbedded mudstone-sandstone are explored. A number of casestudies are included for kaolin, illite and chlorite cements, andthe occurrence of smectite in sandstone is reviewed. Experimentalrate data for clay cements in sandstones are reviewed and there aretwo model-based case studies that address the rates of growth ofkaolinite and illite. The readership of this volume will include sedimentologists andpetrographers who deal with the occurrence, spatial and temporaldistribution patterns and importance of clay mineral cements insandstones, geochemists involved in unraveling the factors thatcontrol clay mineral cement formation in sandstones and petroleumgeoscientists involved in predicting clay mineral distribution insandstones. The book will also be of interest to geologistsinvolved in palaeoclimate studies basin analysis. Latest geochemical data on clays in sandstones Provides important information for geologists involved inbasin analysis, sandstone petrology and petroleum geology If you are a member of the International Association ofSedimentologists (IAS), for purchasing details, please see:http://www.iasnet.org/publications/details.asp?code=SP34

Available in PDF, EPUB and Kindle. Book excerpt: The results are presented of a laboratory study on the cement stabilization of three commonly encountered Virginia soils. The report presents the results of an extensive study of the physical, chemical and mineralogical properties of the three soils. The reaction between the three soils and Portland cement was monitored using unconfined compressive strength, x-ray diffraction, petrographic microscope observations and chemical analysis of acid and water leachates from soil-cement pastes. Some of the conclusions developed by the author are as follows: (1) when the major clay minerals are considered montmorillonitic soils suffered the greatest deterioration from cement treatment, kaolinitic soils less and illitic soils least, (2) iron in the iredell soil appeared to react or dissolve readily with cement, (3) the amount of clay present rather than the type of clay appeared to affect the short term strength development, and (4) three mechanisms responsible for reaction of soil and deterioration of soil constituents are offered. These mechanisms are: (a) calcium hydroxide from hydrated cement reacts with clay minerals or amorphous material yielding calcium compounds of silica, alumina and iron; (b) silica, alumina and iron dissolved from soil constituents react with calcium hydroxide forming calcium compounds; and (c) silica, alumina and iron dissolved from soil are physically adsorbed onto partially hydrated cement grains.

Download or read book Clay in Engineering Geology written by J.E. Gillott and published by Elsevier. This book was released on 2012-12-02 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: Engineering geology is an interdisciplinary subject concerned with the application of geological science to engineering practice, and it is therefore important for the engineering geologist to recognize the boundary between engineering application and purely scientific enquiry. Much research in applied clay science results from imperfectly understood engineering behaviour. Engineering geology is most closely allied to the geotechnical and materials areas of civil engineering. The scope of the present book is limited to the influence of clay but because clay is almost ubiquitous in earth materials the subject still remains broad. In soil and rock, clay is the smallest size fraction, but it is that very fact which often determines its major influences on engineering behaviour.In this book the author reviews the importance of clay in engineering geology and summarizes present knowledge in this field. The plan of the book has remained unchanged since the first edition was published in 1968 but the text, diagrams and reference lists have all been extensively updated. The first 5 chapters review the classification, origin, composition, fabric and physical chemistry of clays. Behavioural aspects, covered in the following 4 chapters, include moisture interaction, strength and rheology, soil stabilization and the use of clays as materials. The final 3 chapters describe methods of analysis of clays and soils.Clay in Engineering Geology contains material drawn from a wide variety of sources and, together with its literature review and indexes, will provide much of value to geologists, mineralogists, civil and geotechnical engineers concerned with applied clay science.

Available in PDF, EPUB and Kindle. Book excerpt: This book is an attempt to provide a comprehensive and coherent description of three widely separated aspects of clays: the science of clays; the industrial uses of clays; and the role of clays in the environment. Most of the existing literature lacks such an integrated study and this work endeavours to fill that gap. An exhaustive account of the science of clays is presented in Part I of the book, which includes the classification, origin and evolution, composition and internal structure, chemical and physical properties of clays; soil mechanics; and analytical techniques for determining clay constituents. Part II provides a comprehensive description of the applications of clays and their derivatives in various industries, while Part III describes the role of clays in the environment; the pollution caused by clay minerals; and the application of clays in order to prevent environmental hazards. A principal feature of the book is its explanation of how the structure and composition of particular clay types facilitate their specific industrial or environmental applications, thus describing the interrelationship between three widely varying aspects of clay. A number of thought-provoking questions are raised at the end of the work in order to leave readers with a better insight in this regard.

Book excerpt: Of huge relevance in a number of fields, this is a survey of the different processes of soil clay mineral formation and the consequences of these processes concerning the soil ecosystem, especially plant and mineral. Two independent systems form soil materials. The first is the interaction of rocks and water, unstable minerals adjusting to surface conditions. The second is the interaction of the biosphere with clays in the upper parts of alteration profiles.
