This book was released on 2012-12-06 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymeric products are used widely in the construction industry, because they offer a range of desirable performance properties not available from traditional materials. Development of these products continues in a number of major research and development programmes within the construction materials sector, aimed at improving the performance, durability and applicational properties of these materials. It seems certain that their use will increase as their overall performance is developed and as the industry becomes more familiar with the techniques required to apply these materials and the benefits they offer. The purpose of this book is to familiarise the reader with the range of thermosetting polymeric materials available for construction applications, and to provide sound information on the properties and applications of these important materials. Professional engineers involved in the specification, application and testing of these materials will find this book a compact, authoritative and comprehensive source of information on these materials. Chemists and technologists involved in developing new or improved formulations will find in this book much to inform their work, particularly in the important area of applicational properties.

Download or read book Salt Water Aging Bonding and In Service Performance of a Novel Poured Silicone Expansion Joint Sealant for Small Movement Bridges written by Dominic Kruszewski and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: According to ASCE’s 2013 Infrastructure Report Card, over 200 million trips are taken daily over a structurally deficient bridge in the United States. One of the most commonly observed degradation factors that contribute to compromising the structural integrity of bridges includes leaking expansion joints which allow water, debris and deicing corrosive materials to penetrate through to the substructure. These corrosive agents can significantly damage the bearing and other key components of the bridge, hindering the lifespan of the structure. Currently, poured silicone sealant joint systems must be replaced every 2-3 years in Connecticut. A novel silicone foam sealant has been developed to provide a long term, cost effective sealing method for small movement expansion joints. The foam sealant, developed by chemically modifying the commercially available silicone sealant developed by Watson Bowman Acme Corp. (termed â€solid sealant†herein), expands approximately 70% of its initial volume allowing for significant material savings compared to the existing product. Furthermore, the stress modulus of the foam sealant was observed to be significantly lower than that of the solid sealant, yielding reduced stresses at the interaction surface between the sealant and the substrate. This research work presents the laboratory experiments conducted to compare the bonding properties of the foam and solid sealant, as detachment from the substrate is a major concern. Each experiment contained some combination of variables such as varying substrate materials and primer application. A five-month aging study was performed to observe the adhesion characteristics of both sealants with and without the presence of road salt as a function of accelerated aging. The salt water aging experiment revealed that the application of primer onto the contact surface of the substrate yielded no significant difference in tensile and/or adhesion performance. The solid sealant’s ultimate strain did not improve and the failure mode was almost always characteristically adhesive. Similarly, the ultimate strain of the foam sealant did not significantly change when primer was applied, and the cohesive failure mode was also consistent regardless of primer treatment. Both sealants, however, exhibited a reduced ultimate stress and while the ultimate strain increased as a function of aging. Additionally, through the assistance of the Connecticut Department of Transportation, the foam sealant expansion joint system was installed on three bridges throughout the state to assess its performance under real conditions including environmental and vehicular effects. Both sealants were installed in a systematic manner to allow for direct comparison of their performance under the same conditions. Finally, field monitoring of the expansion joints was performed to understand the movement of each joint gap and determine whether the foam sealant can be considered as an effective sealing system under these demands while also monitoring the performance of the solid sealant. After several site visits, a few cohesive failures were observed in both sealants which were installed on the bridge with the largest joint gap. Two of these failures were located where the solid sealant was installed, while one failure occurred in the foam sealant. All three bridges are still undergoing consistent monitoring and visual inspection.

Download or read book Handbook of Adhesives and Sealants written by Edward M. Petrie and published by McGraw Hill Professional. This book was released on 2007-01-02 with total page 1075 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Adhesives and Sealants, 2nd Edition is primarily written to assist all those who have a permanent or temporary interest in adhesives and sealants. For those new to the field, the Handbook will provide a fundamental knowledge base of materials and processes as well as reasons why they work and (more importantly) why they don’t work. To the more experienced reader, the breadth and thoroughness of the Handbook will provide a way to reduce time spent on trial and error development or on searching for the optimal recommended process. For the academic, the Handbook will connect the important theories regarding surface science, polymeric materials, and mechanics with practical products and applications of commercial significance. This edition includes major new sections on radiation curable adhesive, biological and naturally occurring adhesives, inorganic adhesives, role of bulk properties of the adhesive, non-destructive testing, and industrial application methods. A completely new chapter is devoted to adhesives used in various industries such as automobile, electrical / electronic, construction, packaging, aerospace, household do-it-yourself, and medical.

Available in PDF, EPUB and Kindle. Book excerpt: Over the concluding decades of the twentieth century, the historic preservation community increasingly turned its attention to modern buildings, including bungalows from the 1930s, gas stations and diners from the 1940s, and office buildings and architectural homes from the 1950s. Conservation efforts, however, were often hampered by a lack of technical information about the products used in these structures, and to fill this gap Twentieth-Century Building Materials was developed by the U.S. Department of the Interior’s National Park Service and first published in 1995. Now, this invaluable guide is being reissued—with a new preface by the book’s original editor. With more than 250 illustrations, including a full-color photographic essay, the volume remains an indispensable reference on the history and conservation of modern building materials. Thirty-seven essays written by leading experts offer insights into the history, manufacturing processes, and uses of a wide range of materials, including glass block, aluminum, plywood, linoleum, and gypsum board. Readers will also learn about how these materials perform over time and discover valuable conservation and repair techniques. Bibliographies and sources for further research complete the volume. The book is intended for a wide range of conservation professionals including architects, engineers, conservators, and material scientists engaged in the conservation of modern buildings, as well as scholars in related disciplines.
