Book excerpt: El objetivo de este Proyecto Final de Grado es mejorar el comportamiento de los morteros epoxídicos a altas temperaturas. Para ello se someten a estudio diferentes formulaciones de mortero epoxídico, partiendo de una base de mortero simple sin aditivar e incorporando diferentes retardantes de llama, con la finalidad de obtener morteros poliméricos con un mejor comportamiento al fuego sin que se vean afectadas las propiedades mecánicas de estos. Con este fin se han realizado ensayos mecánicos y de reacción al fuego para así poder caracterizar el comportamiento de las diferentes probetas y estudiar los diferentes comportamientos según su formulación. Para la caracterización mecánica, sometimos las diferentes probetas a flexotracción con carga puntual centrada y posteriormente, las mitades obtenidas a compresión. Para estudiar la adherencia del mortero epoxídico con el mortero de cemento portland, se prepararon probetas mixtas (mitad de mortero de cemento portland y la otra mitad de los diferentes morteros epoxídicos) a flexotracción con carga bipuntual. Los ensayos mecánicos se realizaron tanto a temperatura ambiente como a 80oC, ya que es alrededor de esta temperatura donde tiene lugar la transición vítrea y sufren un cambio viscoelástico pudiendo producir una disminución de las propiedades del mortero, así como la pérdida de adherencia a las superficies aplicadas. En cuanto al estudio del comportamiento al fuego, sometimos probetas al cono calorimétrico y al ensayo de goteo, para poder observar los diferentes tiempos de ignición, así como la cantidad de calor liberada por éstas. Tras estos ensayos, comprobamos cómo la presencia de retardantes de llama en los morteros epoxídicos no altera negativamente el comportamiento de este a temperatura ambiente y mejora las propiedades mecánicas del mortero epoxídico a la temperatura de transición vítrea. Además pudimos observar que se retrasa el tiempo de ignición y que la cantidad de calor liberada disminuye.

Download or read book Soil Mechanics written by David Muir Wood and published by Cambridge University Press. This book was released on 2009-09-28 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book teaches the principles of soil mechanics to undergraduates, along with other properties of engineering materials, to which the students are exposed simultaneously. Using the critical state method of soil mechanics to study the mechanical behavior of soils requires the student to consider density alongside effective stresses, permitting the unification of deformation and strength characteristics. This unification aids the understanding of soil mechanics. This book explores a one-dimensional theme for the presentation of many of the key concepts of soil mechanics - density, stress, stiffness, strength, and fluid flow - and includes a chapter on the analysis of one-dimensional consolidation, which fits nicely with the theme of the book. It also presents some theoretical analyses of soil-structure interaction, which can be analyzed using essentially one-dimensional governing equations. Examples are given at the end of most chapters, and suggestions for laboratory exercises or demonstrations are given.

Download or read book Meat Science written by R. A. Lawrie and published by Elsevier. This book was released on 2013-10-22 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Meat Science, Fourth Edition focuses on the science of meat, from the initiation of life in the meat animal to the absorption of its nutrients by the human consumer. This edition updates the topics on hormonal control of reproduction and growth, pre-slaughter stress, modes of stunning and bleeding, refrigeration, eating quality, and consumer health. A section has been added on the electrical stimulation of carcasses post-mortem, emphasizing the differing susceptibility of individual muscles to cold shock on the one hand and to undergo conditioning changes on the other. The developments, such as the mechanical recovery of meat, its modification by high pressure, its reformation after controlled comminution, and incorporation with it of proteins from abattoir waste or non-meat sources are also elaborated in this book. This publication is beneficial to students and individuals researching on the food science of meat.
