Concrete is an inherently complex material to produce and an even more complex material to repair. With growing pressure to maintain the built environment, and not simply to demolish and rebuild, the need to repair concrete buildings and other structures is increasing and is expected to become of greater importance in the future. This straightforward book serves as a practical guide to engineers on the processes to be followed in commissioning a concrete repair. It stresses the need to fully understand the cause, extent and location of the problem, by appropriate insitu and laboratory testing. And it outlines the steps to a successful repair. It includes sections on the different repair techniques, giving good practical advice as to where and when to use them, and the warns of the pitfalls of their incorrect use. It also includes an up-to-date guide on the current standards for repair, and provides a good bibliography on other sources of information and books on the various techniques.

A Practical Guide to Maintenance Carrying a billion-dollar price tag, corrosion of reinforced concrete is the enemy of every country’s investment in real estate. The widespread and long-term use of reinforced concrete makes its correct and proper examination, maintenance, and repair paramount. Steel-Reinforced Concrete Structures: Assessment and Repair of Corrosion explains the corrosion of reinforced concrete from a practical point of view, highlighting protective design and repair procedures. The book begins with a discussion of the corrosion phenomena, the effect of concrete properties on corrosion, and the precautions available in the construction stage to mitigate corrosion. It covers the theoretical and practical methods in evaluating the concrete structures and new, practical methods to protect steel reinforcement. The book also includes methods established in the last decade that provide new ways of protecting steel-reinforced bars and the traditional and advanced repairing methods. The author explains the importance of implementing an integrity management system to provide a comprehensive maintenance strategy and concludes with coverage of the traditional, time-tested, and advanced repair techniques. A special feature is a chapter focusing on the advance maintenance plan philosophy and risk-based maintenance for reinforced concrete structures. The author examines economic analysis procedures and the probability of structural failures to define structure risk assessment. He covers precautions and recommendations for protecting the reinforced concrete structures from corrosion based on codes and specifications. He uses case histories from all over the world to demonstrate the widespread application and range of advanced repair techniques and presents a practical guide to the maintenance of concrete structures. The book provides procedures for corrosion diagnosis and determining the appropriate methods for repair, as well as economic models for on-site decision making.

It is estimated that 225,000 bridges, including nearly 40% of highway bridges, in the United States today are structurally deficient or functionally obsolete. While the urgency of this problem has begun to be acknowledged at official levels, and more public funds set aside for bridge inspection and rehabilitation, the need remains for engineers versed in contemporary rehabilitation methods. Unfortunately, until the publication of this book, engineers’ efforts to educate themselves in the field have been thwarted by the fact that good, up-to-date material on bridge inspection and repair could be obtained only through a painstaking search through hundreds of specialized publications. Edited by Louis G. Silano, P.E., Senior Vice President and Technical Director of Structures with the firm of Parsons Brinckerhoff. Bridge Inspection and Rehabilitation: A Practical Guide is the first and only "A-to-Z" guide to practical aspects of bridge inspection and rehabilitation.

The Concrete Solutions series of International Conferences on Concrete Repair began in 2003 with a conference held in St. Malo, France in association with INSA Rennes. Subsequent conferences have seen us partnering with the University of Padua in 2009 and with TU Dresden in 2011. This conference is being held for the first time in the UK, in association with Queen’s University Belfast and brings together delegates from 36 countries to discuss the latest advances and technologies in concrete repair. Earlier conferences were dominated by electrochemical repair, but there has been an interesting shift to more unusual methods, such as bacterial repair of concrete plus an increased focus on service life design aspects and modelling, with debate and discussion on the best techniques and the validity of existing methods. Repair of heritage structures is also growing in importance and a number of the papers have focused on the importance of getting this right, so that we may preserve our rich cultural heritage of historic structures. This book is an essential reference work for those working in the concrete repair field, from Engineers to Architects and from Students to Clients.
