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 comprises the proceedings of the Third International Conference on Calcined Clays for Sustainable Concrete held in New Delhi, India in October 2019. The papers cover topics related to geology of clay, hydration and performance of blended systems with calcined clays, alkali activated binders, and economic and environmental impacts of the use of calcined clays in cement-based materials. The book presents research on influence of processing on reactivity of calcined clays, influence of clay mineralogy on reactivity, geology of clay deposits, and the environmental impact of use of calcined clays in cement and concrete and field applications of calcined clay in concrete. Apart from giving an overview of the progress of research during the last two years, this work also covers the state-of-the art on the practical aspects of production and use of calcined clays in construction. The contents of this volume will prove useful to researchers and graduate students working in the areas of cement chemistry, cement production, and concrete design.

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 systems 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 fields. 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.
