This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: [CASTELLÀ] Los elevados índices de actividad que ha alcanzado el sector de la construcción en España en las últimas décadas han provocado un gran incremento de los residuos de construcción y demolición (RCD). Debido a los múltiples problemas ambientales que originan, resulta imprescindible reciclar estos productos con el fin de aprovechar su potencial y permitir un desarrollo más sostenible de la actividad constructora. Para facilitar la reincorporación de los RCD en el mercado, es necesario llevar a cabo una serie de estudios sobre las características de los áridos reciclados así como sobre las propiedades del hormigón fabricado con estos, en particular su durabilidad. La durabilidad de las estructuras de hormigón armado depende esencialmente de la de sus armaduras y, por tanto, de la resistencia de éstas a la corrosión. La acción de los cloruros puede producir una corrosión localizada por picaduras, causando serias patologías en las estructuras. En esta presente tesina se estudia la fijación de cloruros de los Residuos de Construcción y Demolición (RCD) y su influencia en la difusión de cloruros en hormigones con áridos reciclados. Para realizar este estudio, se han sometido distintos tipos de materiales, áridos reciclados de hormigón, pastas de cemento, morteros y hormigones, a una inmersión en una solución de cloruro de sodio. El principal objetivo de esta tesina experimental es valorar la influencia de los áridos reciclados en la penetración de cloruros en hormigones fabricados con estos, por lo que es necesario evaluar la capacidad de absorción y fijación de cloruros de los materiales previamente citados. La metodología que se ha seguido para la realización de los ensayos se ha basado en la utilización de la misma solución salina y de los mismos tiempos de exposición para la totalidad de las muestras. Las pastas de cemento, los morteros y los hormigones se han fabricado modificando la relación agua/cemento y, excepto para las pastas de cemento, variando asimismo la cantidad de árido reciclado empleado. Después del ataque salino, en el caso de los áridos, las pastas y los morteros, se ha determinado la cantidad de cloruros totales y de cloruros solubles de cada una de las muestras. Los cloruros fijados se obtienen mediante la diferencia de los dos valores anteriores. Complementariamente, se ha realizado el análisis composicional y visual de los distintos materiales, mediante ensayos de difracción de rayos X y microscopía electrónica. En el caso de los hormigones, se ha medido el frente de penetración de los cloruros. Los resultados obtenidos dentro de esta tesina experimental han sido concluyentes. La presencia de áridos reciclados en los hormigones influye en su durabilidad, reduciendo la resistencia a la penetración de cloruros en el caso de relaciones a/c bajas. En caso contrario, relaciones a/c altas, no se observa ninguna diferencia apreciable entre el uso de árido convencional y el uso de árido reciclado.

Download or read book Application of Bacterial Pigments as Colorant written by Wan Azlina Ahmad and published by Springer Science & Business Media. This book was released on 2011-10-14 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental concerns regarding continuous use of synthetic dyes saw a revival in the demand for natural dyes as natural dyes exhibit better biodegradability and generally have a higher compatibility with the environment. However, one of the limitations on the use of natural dyes or pigments is the low extraction yield factors (a few grams of pigment per kg of dried raw material). Therefore, the exploitation of other biological sources such as fungi, bacteria and cell cultures offers interesting alternative. Microbial pigments such as from bacterial origins offer the advantage in terms of production compared to pigments extracted from vegetables or animals, due to its simple cell and fast culturing technique. This book offers interesting insight into initial works carried out to demonstrate the potential use of bacterial pigment as colorant for various applications.

Download or read book Asphalt Pavements written by Devendra Damale and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Asphalt pavements are easy to maintain, quick to construct, and provide a safe, smooth, quiet ride. Simply put, asphalt pavements provide the greatest level of drivability at the most economical price. Asphalt pavement refers to any paved road surfaced with asphalt. Hot Mix Asphalt (HMA) is a combination of approximately 95% stone, sand, or gravel bound together by asphalt cement, a product of crude oil. Asphalt cement is heated aggregate, combined, and mixed with the aggregate at an HMA facility. Asphalt is America's most recycled material. Reclaimed asphalt is not just reusable as a "black rock" the asphalt cement in the reclaimed pavement is reactivated to become an integral part of the new pavement.

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.
