Corrosion of Reinforcement in Concrete ConstructionC. L. Page, P. B. Bamforth, J. W. Figg The corrosion of reinforcement in concrete is the single most important cause of concrete structures needing repair. In the UK alone, it is estimated that repairs to damaged concrete cost over ú500 million each year. Furthermore, inherited problems of corrosion in existing concrete structures are likely to increase as we approach the 21st century. Significant progress has been made in recent years in the early detection of corrosion problems and in cost-effective preventative measures. The high quality of research in Corrosion of Reinforcement in Concrete Construction reflects the worldwide growth of interest in this subject. The topics covered embrace virtually all aspects of steel corrosion in concrete and its control. In particular, it covers the following themes: Corrosion mechanisms; monitoring methods; performance and durability of various concretes; practical aspects of remedial and preventative methods; electrochemical rehabilitation techniques; coatings and treatments for corrosion inhibition; the economics of corrosion prevention; case studies and long-term durability investigations. This key book represents a compilation of the latest knowledge in this rapidly developing field, and highlights areas for further research. It will serve as an essential source of reference both for the research community and for practising engineers. |
