Concrete And Clay

An interdisciplinary account of the environmental history and changing landscape of New York City. In this innovative account of the urbanization of nature in New York City, Matthew Gandy explores how the raw materials of nature have been reworked to produce a "metropolitan nature" distinct from the forms of nature experienced by early settlers. The book traces five broad developments: the expansion and redefinition of public space, the construction of landscaped highways, the creation of a modern water supply system, the radical environmental politics of the barrio in the late 1960s and early 1970s, and the contemporary politics of the environmental justice movement. Drawing on political economy, environmental studies, social theory, cultural theory, and architecture, Gandy shows how New York's environmental history is bound up not only with the upstate landscapes that stretch beyond the city's political boundaries but also with more distant places that reflect the nation's colonial and imperial legacies. Using the shifting meaning of nature under urbanization as a framework, he looks at how modern nature has been produced through interrelated transformations ranging from new water technologies to changing fashions in landscape design. Throughout, he considers the economic and ideological forces that underlie phenomena as diverse as the location of parks and the social stigma of dirty neighborhoods.

This volume focuses on research and practical issues linked to Calcined Clays for Sustainable Concrete. The main subjects are geology of clays, hydration and performance of blended system with calcined clays, alkali activated binders, economic and environmental impacts of the use of calcined clays in cement based materials. Topics addressed in this book include the influence of processing on reactivity of calcined clays, influence of clay mineralogy on reactivity, geology of clay deposits, Portland-calcined clay systems, hydration, durability, performance, Portland-calcined clay-limestone systems, hydration, durability, performance, calcined clay-alkali systems, life cycle analysis, economics and environmental impact of use of calcined clays in cement and concrete and field applications. This book compiles the different contributions of the 1st International Conference on Calcined Clays for Sustainable Concrete, which took place in Lausanne, Switzerland, June, 23-25, 2015.The papers present the latest research in their field. It contains nearly 80 papers and abstracts. Overall, this work gives a broad view of research on calcined clays in the field of construction and will stimulate further research into calcined clays for sustainable concrete.

Starting with the receipt of materials and continuing all the way through to the final completion of the construction phase, Concrete and Steel Construction: Quality Control and Assurance examines all the quality control and assurance methods involving reinforced concrete and steel structures. This book explores the proper ways to achieve high-quality construction projects, and also provides a strong theoretical and practical background. It introduces information on quality techniques and quality management, and covers the principles of quality control. The book presents all of the quality control and assurance protocols and non-destructive test methods necessary for concrete and steel construction projects, including steel materials, welding and mixing, and testing. It covers welding terminology and procedures, and discusses welding standards and procedures during the fabrication process, as well as the welding codes. It also considers the total quality management system based on ISO 9001, and utilizes numerous international and industry building standards and codes. Covers AISC, ACI, BS, and AWS codes Examines methods for concrete quality control in hot and cold weather applications, as well as material properties Illustrates methods for non-destructive testing of concrete and for steel welding—radiographic, ultrasonic, and penetration and other methods. Addresses ISO 9001 standards—designed to provide organizations better quality control systems Includes a checklist to be considered as a QA template Developed as a handbook for industry professionals, this book also serves as a resource for anyone who is working in construction and on non-destructive inspection testing for concrete and steel structures.
