Provides a general account of the factors which cause decay of building stones and a summary of the best methods to reduce the incidence of decay. It discusses weathering associated with natural defects inherent in stone and examines issues of weathering caused by bad workmanship or errors in the selection of material. Decay through chemical and natural physical phenomena are discussed in detail. The final sections offer useful advice on how to prevent long term decay through appropriate repair, replacement and cleaning of stone.
The readers of the first two editions of Stone: Properties, Durabi lity in Man's Environment, were mostly architects, restoration architects of buildings and monuments in natural stone, profes sionals who sought basic technical information for non-geologists. The increasing awareness of rapidly decaying monuments and their rescue from loss to future generations have urged this writer to update the 1973 and 1975 editions, now unavailable and out of print. Due to the 20-year-Iong interval, extensive updating was necessary to produce this new book. The present edition concentrates on the natural material stone, as building stone, dimension stone, architectural stone, and decorative field stones. Recently, the use of stone for thin curtain walls on buildings has become fashionable. The thin slabs exposed to anew, unknown complexity of stresses, resulting in bowing of crystalline marble, has attracted much negative pUblicity. The costs of replacing white slabs of marble on entire buildings with its legal implications have led construction com panies into bankruptcy. We blame many environmental problems on acid rain. Does acid rain really accelerate stone decay that much? Stone preservation is being attempted with an ever-increasing number of chemicals applied by as many specialists to save crumbling stone. Chemists filled this need during a time of temporary job scarcity, while the general geologist missed this opportunity; he was too deeply involved in the search for fossil fuels and metals.
First published in 1996, this volume has been substantially updated to reflect new research in the conservation of stone monuments, sculpture, and archaeological sites.
Transporting readers from derelict homesteads to imperiled harbors, postindustrial ruins to Cold War test sites, Curated Decay presents an unparalleled provocation to conventional thinking on the conservation of cultural heritage. Caitlin DeSilvey proposes rethinking the care of certain vulnerable sites in terms of ecology and entropy, and explains how we must adopt an ethical stance that allows us to collaborate with—rather than defend against—natural processes. Curated Decay chronicles DeSilvey’s travels to places where experiments in curated ruination and creative collapse are under way, or under consideration. It uses case studies from the United States, Europe, and elsewhere to explore how objects and structures produce meaning not only in their preservation and persistence, but also in their decay and disintegration. Through accessible and engaging discussion of specific places and their stories, it traces how cultural memory is generated in encounters with ephemeral artifacts and architectures. An interdisciplinary reframing of the concept of the ruin that combines historical and philosophical depth with attentive storytelling, Curated Decay represents the first attempt to apply new theories of materiality and ecology to the concerns of critical heritage studies.
This series includes monographs, research results, and state-of-the-art reviews of conservation literature by Institute staff and others.Discusses the types and causes of stone biodeterioration in hot and humid climates, preventive and remedial methods, selection of chemical treatments, status of current research, and areas for further investigation.
Sustainability of Construction Materials, Second Edition, explores an increasingly important aspect of construction. In recent years, serious consideration has been given to environmental and societal issues in the manufacturing, use, disposal, and recycling of construction materials. This book provides comprehensive and detailed analysis of the sustainability issues associated with these materials, mainly in relation to the constituent materials, processing, recycling, and lifecycle environmental impacts. The contents of each chapter reflect the individual aspects of the material that affect sustainability, such as the preservation and repair of timber, the use of cement replacements in concrete, the prevention and control of metal corrosion and the crucial role of adhesives in wood products. - Provides helpful guidance on lifecycle assessment, durability, recycling, and the engineering properties of construction materials - Fully updated to take on new developments, with an additional nineteen chapters added to include natural stone, polymers and plastics, and plaster products - Provides essential reading for individuals at all levels who are involved in the construction and selection, assessment and use, and maintenance of materials
