This book deals with the diagnosis, prognosis and repair issues associated with concrete buildings. Since the patenting and subsequent large--scale manufacture of modern cement, in the nineteenth century, concrete has become one of the most widely used construction materials in the world. Those concerned with building pathology now need to understand problems specifically related to concrete and to identify appropriate methods of repair and remediation. This book brings together experts in the history, defect diagnosis, remediation and maintenance of concrete. It includes case studies from around the world to illustrate the various repair methods available. It will provide an invaluable guide for architects, building surveyors, structural engineers and specialist contractors as well as students of building pathology and conservation.
