The deterioration of cement and concrete as a result of the alkali-silica reaction (concrete cancer) is one of the major problems facing civil, structural and mechanical engineers involved in the design, construction, repair and maintenance of structures. It is a global problem, and in this book, case studies from both developed and developing countries have been selected to provide an insight into how variables such as climate, geology, construction materials and methods, and building practice, have a bearing on the magnitude of the problem and an influence on remedial measures.
