This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Los hormigones porosos se caracterizan por su elevada porosidad. Por un lado, los vacíos generados pueden contribuir a la permeabilidad del material, dándole funcionalidad drenante. Por otro lado, esto también conlleva una reducción de las propiedades mecánicas. El equilibrio entre el comportamiento mecánico y la permeabilidad está relacionado con la composición de la mezcla y con el grado de compactación durante la ejecución. Teniendo esto en cuenta, el objetivo del presente estudio es evaluar la relación entre la compactación y el comportamiento del material. En este trabajo final de grado se busca profundizar en el comportamiento del hormigón poroso. La caracterización del material se antoja indispensable para hacer del hormigón poroso un material de uso común y estandarizado. Para poder evaluar la relación entre la compactación y el comportamiento del material se realizó una campaña experimental en la cual las variables de estudio fueron el grado de compactación de las probetas y la cantidad de cemento aplicada a la mezcla. Así se pudo evaluar la influencia del proceso de compactación y de la dosificación de materiales en el comportamiento general del material y en sus propiedades. Se centró la investigación en la influencia de estos factores sobre las propiedades hidráulicas (a través de la permeabilidad) y de las propiedades mecánicas (a través de la resistencia a compresión y a tracción). Se fabricaron 120 probetas de hormigón poroso, que se dividieron en 12 tipologías según las variables del estudio. Así se pudo estudiar claramente cómo afecta cada variable. Además de la campaña experimental, se realizó una documentación previa con toda la información de investigaciones existentes que guardase relación con lo que se trabajó en el estudio. Se hizo una búsqueda para encontrar autores que trabajaron el proceso de compactación en hormigones porosos con anterioridad. La idea fue aportar toda la información necesaria para que el lector entienda los resultados de la campaña experimental y comprenda el análisis de dichos resultados. Los resultados muestran que el grado de compactación es el factor determinante en todas las propiedades del hormigón poroso. Las perspectivas de mejora del material pasan por encontrar un método numérico que encuentre, para cada caso particular, el proceso de compactación óptimo, obteniendo el equilibrio entre el valor de permeabilidad y el valor de resistencia mecánica.

Download or read book Construction and Building Research written by Carmen Llinares-Millán and published by Springer Science & Business Media. This book was released on 2014-01-31 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many areas of knowledge converge in the building industry and therefore research in this field necessarily involves an interdisciplinary approach. Effective research requires strong relation between a broad variety of scientific and technological domains and more conventional construction or craft processes, while also considering advanced management processes, where all the main actors permanently interact. This publication takes an interdisciplinary approach grouping various studies on the building industry chosen from among the works presented for the 2nd International Conference on Construction and Building Research. The papers examine aspects of materials and building systems; construction technology; energy and sustainability; construction management; heritage, refurbishment and conservation. The information contained within these pages may be of interest to researchers and practitioners in construction and building activities from the academic sphere, as well as public and private sectors.

This book was released on 2006-06-07 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Formal decision and evaluation models are so widespread that almost no one can pretend not to have used or suffered the consequences of one of them. This book is a guide aimed at helping the analyst to choose a model and use it consistently. A sound analysis of techniques is proposed and the presentation can be extended to most decision and evaluation models as a "decision aiding methodology".

Available in PDF, EPUB and Kindle. Book excerpt: For information on the online course in Biological Wastewater Treatment from UNESCO-IHE, visit: http://www.iwapublishing.co.uk/books/biological-wastewater-treatment-online-course-principles-modeling-and-design Over the past twenty years, the knowledge and understanding of wastewater treatment have advanced extensively and moved away from empirically-based approaches to a first principles approach embracing chemistry, microbiology, physical and bioprocess engineering, and mathematics. Many of these advances have matured to the degree that they have been codified into mathematical models for simulation with computers. For a new generation of young scientists and engineers entering the wastewater treatment profession, the quantity, complexity and diversity of these new developments can be overwhelming, particularly in developing countries where access is not readily available to advanced level tertiary education courses in wastewater treatment. Biological Wastewater Treatment addresses this deficiency. It assembles and integrates the postgraduate course material of a dozen or so professors from research groups around the world that have made significant contributions to the advances in wastewater treatment. The book forms part of an internet-based curriculum in biological wastewater treatment which also includes: Summarized lecture handouts of the topics covered in book Filmed lectures by the author professors Tutorial exercises for students self-learning Upon completion of this curriculum the modern approach of modelling and simulation to wastewater treatment plant design and operation, be it activated sludge, biological nitrogen and phosphorus removal, secondary settling tanks or biofilm systems, can be embraced with deeper insight, advanced knowledge and greater confidence.
