This volume traces the process by which reinforced concrete emerged during the 19th century as the successful building material of today. Early work on testing the strength of cements led into a period of experimental work by a number of engineers, notably in Britain, France and America, to devise successful systems of embedding iron in concrete in such a way that the two materials would act together to carry imposed loads. The papers take the story to the early years of the 20th century and provide a thorough review of the gradual evolution of ideas and the contributions of individuals to this technology.
Examining the proliferation of reinforced-concrete construction in the United States after 1900, historian Amy E. Slaton considers how scientific approaches and occupations displaced traditionally skilled labor. The technology of concrete buildings—little studied by historians of engineering, architecture, or industry—offers a remarkable case study in the modernization of American production. The use of concrete brought to construction the new procedures and priorities of mass production. These included a comprehensive application of science to commercial enterprise and vast redistributions of skills, opportunities, credit, and risk in the workplace. Reinforced concrete also changed the American landscape as building buyers embraced the architectural uniformity and simplicity to which the technology was best suited. Based on a wealth of data that includes university curricula, laboratory and company records, organizational proceedings, blueprints, and promotional materials as well as a rich body of physical evidence such as tools, instruments, building materials, and surviving reinforced-concrete buildings, this book tests the thesis that modern mass production in the United States came about not simply in answer to manufacturers' search for profits, but as a result of a complex of occupational and cultural agendas.
Cement and concrete are of great interest to the construction and civil engineering communities. This study provides an appreciation of the complex nature of these materials and a realization that most of the failures involving concrete constructions are preventable.
Measuring the long-term durability of new types of concrete and concrete technologies is crucial to their acceptance in the marketplace. This long-needed handbook of analytical techniques provides a complete reference to the cutting-edge procedures used to test today's innovative materials. Ranging from chemical and thermal analysis, to IR and Nuclear Magnetic Resonance spectroscopy, to Scanning Electron Microscopy, x-ray diffraction, computer modeling and more, the book provides first-hand explanations of modern methodsùcontributed by 24 leading scientists, many of whom actually developed or refined the techniques. The book includes many analytic techniques, applied to a wide range of organic, inorganic and composite materials and additives.Perfect for practitioners, students, and professional standards writers, the handbook is highly useful for scrutinizing materials in a variety of environments. It takes into account the many factors that affect the qualities of concreteùtemperature, pore and pore-size distribution, surface area, and exposureùgathering diverse evaluation methods into one convenient resource.
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.
