CiNii Books - Durability of concrete and cement composites

Concrete and other cement-based composites are by far the most widely used man-made construction materials in the world. However major problems of infrastructure deterioration have been caused by unanticipated premature degradation of these materials. Durability of Concrete and Cement Composites provides an up-to-date analysis of several of the main forms of degradation, examining what is known about their causes and control. The book begins with a review of the physical and chemical characteristics of cement-based materials then moves on to discuss specific forms of degradation. It also examines trends in modelling and prediction of service-lives.

Description

Whilst most structures made using concrete and cement-based composites have not shown signs of premature degradation, there have been notable exceptions. In addition, there is increasing pressure for new structures to remain in serviceable condition for long periods with only minimal maintenance before being recycled. All these factors have highlighted the issues of what affects the durability of these materials in different circumstances and how material properties can be measured and improved. Durability of concrete and cement composites summarises key research on these important topics. After an introductory chapter, the book reviews the pore structure and chemistry of cement-based materials, providing the foundation for understanding the particular aspects of degradation which are discussed in the following chapters. These include dimensional stability and cracking processes, chemical and microbiological degradation of concrete, corrosion of reinforcing and prestressing steels, deterioration associated with certain aggregates, effects of frost and problems involving fibre-reinforced and polymer-cement composites. With its distinguished international team of contributors, Durability of concrete and cement composites is a standard reference for all those concerned with improving the service life of structures using these materials.
