Book excerpt: El concreto asf�ltico es un material artificial producto del endurecimiento de la mezcla de cemento asf�ltico(convencional o modificado) con agregados p�treos (gravas, arenas y finos), que es colocada y compactada bajocondiciones de temperatura controlada. Su uso se extiende a aplicaciones carreteras e hidr�ulicas tales como n�cleosy revestimientos en presas, revestimientos de canales, embalses y lagos.En este cap�tulo se presentan conceptos generales relativos al concreto asfaltico, tales como los materiales quelo conforman, propiedades y usos. Se presentan adem�s, los procedimientos de laboratorio utilizados para lacaracterizaci�n del cemento asf�ltico, agregados p�treos as� como del concreto asf�ltico. Finalmente, se describen loslineamientos para la selecci�n de materiales y dise�o volum�trico de mezclas asf�lticas utilizadas en la construcci�nde barreras impermeables, los cuales incluyen la caracterizaci�n f�sica y mec�nica del material.

This book was released on 2017-12-07 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Se hace una descripción de lo que es el CCR, sus aplicaciones y las ventajas y limitaciones que tiene el empleo de este material. Se describen las características que requieren tener los materiales componentes del concreto, las consideraciones que se deben tomar en cuenta al hacer el proporcionamiento de las mezclas en cuanto a las propiedades que debe alcanzar el concreto, tanto en estado fresco como endurecido; se establecen los métodos recomendados para hacer los proporcionamientos, así como la forma de llevar a cabo las mezclas de prueba en el laboratorio y en campo. Se especifican las propiedades que debe alcanzar el concreto en estado endurecido en cuanto a resistencia, propiedades elásticas, deformación diferida, capacidad de deformación por tensión, cambios volumétricos, propiedades térmicas, permeabilidad, durabilidad y peso unitario. Para el diseño de las presas con CCR se establecen las consideraciones que se deben hacer en cuanto a la sección transversal de la presa, las acciones, los factores de seguridad, sobre el diseño estructural, el control de temperatura, juntas de contracción, galería y socavones, recubrimiento y control de filtraciones, así como sobre el diseño de los vertedores, de las obras de desfogue y sobre la cimentación. En relación con el proceso constructivo se incluyen recomendaciones sobre la producción de agregados, las plantas para la producción de CCR, los sistemas de transporte, los procedimientos de colocación del concreto, las juntas entre capas de concreto, los métodos de compactación, las juntas de contracción, las cimbras y paramentos y sobre la construcción de galerías y drenaje. Por último, en lo relacionado con el control de calidad del CCR, se revisan aspectos sobre las actividades previas a la colocación, durante la colocación y después de la colocación del CCR. Como ayudas de diseño se incluyen un conjunto de formatos que permiten registrar en forma ordenada los resultados de las diferentes actividades relacionadas con este procedimiento constructivo.
Download or read book Geothermal Resources written by R. Bowen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the Arab oil embargo of 1974, it has been clear that the days of almost limitless quantities of low-cost energy have passed. In addition, ever worsening pollution due to fossil fuel consumption, for instance oil and chemical spills, strip mining, sulphur emission and accumulation of solid wastes, has, among other things, led to an increase of as much as 10% in the carbon dioxide content of the atmosphere in this century. This has induced a warming trend through the 'greenhouse effect' which prevents infrared radiation from leaving it. Many people think the average planetary temperatures may rise by 4°C or so by 2050. This is probably true since Antarctic ice cores evidence indicates that, over the last 160000 years, ice ages coincided with reduced levels of carbon dioxide and warmer interglacial episodes with increased levels of the gas in the atmosphere. Consequently, such an elevation of temperature over such a relatively short span of time would have catastrophic results in terms of rising sea level and associated flooding of vast tracts of low-lying lands. Reducing the burning of fossil fuels makes sense on both economic and environmental grounds. One of the most attractive alternatives is geothermal resources, especially in developing countries, for instance in El Salvador where geothermal energy provides about a fifth of total installed electrical power already. In fact, by the middle 1980s, at least 121 geothermal power plants were operating worldwide, most being of the dry steam type.

Available in PDF, EPUB and Kindle. Book excerpt: "The book contains an enormous amount of information — mathematical, bibliographical and historical — interwoven with some outstanding heuristic discussions." — Mathematical Reviews. In this massive graduate-level study, Emeritus Professor Edwards (Australian National University, Canberra) presents a balanced account of both the abstract theory and the applications of linear functional analysis. Written for readers with a basic knowledge of set theory, general topology, and vector spaces, the book includes an abundance of carefully chosen illustrative examples and excellent exercises at the end of each chapter. Beginning with a chapter of preliminaries on set theory and topology, Dr. Edwards then presents detailed, in-depth discussions of vector spaces and topological vector spaces, the Hahn-Banach theorem (including applications to potential theory, approximation theory, game theory, and other fields) and fixed-point theorems. Subsequent chapters focus on topological duals of certain spaces: radon measures, distribution and linear partial differential equations, open mapping and closed graph theorems, boundedness principles, duality theory, the theory of compact operators and the Krein-Milman theorem and its applications to commutative harmonic analysis. Clearly and concisely written, Dr. Edwards's book offers rewarding reading to mathematicians and physicists with an interest in the important field of functional analysis. Because of the broad scope of its coverage, this volume will be especially valuable to the reader with a basic knowledge of functional analysis who wishes to learn about parts of the subject other than his own specialties. A comprehensive 32-page bibliography supplies a rich source of references to the basic literature.

Available in PDF, EPUB and Kindle. Book excerpt: The theory of spatial models over lattices, or random fields as they are known, has developed significantly over recent years. This book provides a graduate-level introduction to the subject which assumes only a basic knowledge of probability and statistics, finite Markov chains, and the spectral theory of second-order processes. A particular strength of this book is its emphasis on examples - both to motivate the theory which is being developed, and to demonstrate the applications which range from statistical mechanics to image analysis and from statistics to stochastic algorithms.
