Steel-reinforced concrete is used ubiquitously as a building material due to its unique combination of the high compressive strength of concrete and the high tensile strength of steel. Therefore, reinforced concrete is an ideal composite material that is used for a wide range of applications in structural engineering such as buildings, bridges, tunnels, harbor quays, foundations, tanks and pipes. To ensure durability of these structures, however, measures must be taken to prevent, diagnose and, if necessary, repair damage to the material especially due to corrosion of the steel reinforcement. The book examines the different aspects of corrosion of steel in concrete, starting from basic and essential mechanisms of the phenomenon, moving up to practical consequences for designers, contractors and owners both for new and existing reinforced and prestressed concrete structures. It covers general aspects of corrosion and protection of reinforcement, forms of attack in the presence of carbonation and chlorides, problems of hydrogen embrittlement as well as techniques of diagnosis, monitoring and repair. This second edition updates the contents with recent findings on the different topics considered and bibliographic references, with particular attention to recent European standards. This book is a self-contained treatment for civil and construction engineers, material scientists, advanced students and architects concerned with the design and maintenance of reinforced concrete structures. Readers will benefit from the knowledge, tools, and methods needed to understand corrosion in reinforced concrete and how to prevent it or keep it within acceptable limits.

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. Analyses a range of materials such as reinforced steel in concrete, pre-stressed concrete and cement composites Discusses key degradation phenomena such as cracking processes and the impact of cold weather conditions A standard reference for those concerned with improving the service life of structures using concrete and cement based composites

The tensile properties of concrete were improved in the middle of the last century when reinforcing steel was first used. Since then, the practice has developed to such an extent that reinforced concrete is now one of the major structural materials available to the construction industry. In general, it has proved successful for both structural performance and durability. As an example of the good long-term performance of reinforced concrete, a warehouse (Fig 1), erected in 1900, was still in good condition when examined in 1979, there being little evidence of cracking or spalling associated with reinforcement corrosion. There are, however, examples of early failure of concrete units as a result of premature reinforcement corrosion (Figs 2 and 3). The reasons for this variability are many; this digest, the first of three parts, outlines the main factors controlling the durability of steel in concrete made with ordinary Portland cement to BS 12. It considers the protection to steel provided by the concrete and the mechanisms which cause this protection to be lost leading to corrosion of the reinforcement. The second part describes the diagnosis of concrete failure and the structural assessment necessary as a result of corrosion. Emphasis is placed on the need for a thorough understanding of the mechanism responsible for deterioration, especially when assessing the extent of further disruption or choosing an appropriate repair technique. The third part considers materials and methods of repair.

This book describes the newest developments in the creation of concrete using smart additives and supplementary cementitious materials as well as methods, technology and novel admixtures to monitor, evaluate and control steel corrosion in reinforced concrete. Industry experts and research specialists explain the structural, physical, and chemical properties of various types of concrete and its applications. They detail the characteristics preferred for manufacturing specific types of concrete. The book chapters also focus on the electrochemical state of the steel reinforcement in view of steel corrosion and corrosion control.

High-strength materials offer alternatives to frequently used materials for high-rise construction. A material of higher strength means a smaller member size is required to resist the design load. However, high-strength concrete is brittle, and high-strength thin steel plates are prone to local buckling. A solution to overcome such problems is to adopt a steel-concrete composite design in which concrete provides lateral restraint to steel plates against local buckling, and steel plates provide confinement to high-strength concrete. Design of Steel-Concrete Composite Structures Using High Strength Materials provides guidance on the design of composite steel-concrete structures using combined high-strength concretes and steels. The book includes a database of over 2,500 test results on composite columns to evaluate design methods, and presents calculations to determine critical parameters affecting the strength and ductility of high-strength composite columns. Finally, the book proposes design methods for axial-moment interaction curves in composite columns. This allows a unified approach to the design of columns with normal- and high-strength steel concrete materials. This book offers civil engineers, structural engineers, and researchers studying the mechanical performance of composite structures in the use of high-strength materials to design and construct advanced tall buildings. Presents the design and construction of composite structures using high-strength concrete and high-strength steel, complementing and extending Eurocode 4 standards Addresses a gap in design codes in the USA, China, Europe and Japan to cover composite structures using high-strength concrete and steel in a comprehensive way Gives insight into the design of concrete-filled steel tubes and concrete-encased steel members Suggests a unified approach to designing columns with normal- and high-strength steel and concrete

Parts 1 and 2 of this digest deal with the mechanism of protection and the diagnosis and assessment of deterioration of reinforcing steel in concrete made with ordinary Portland cement to BS 12. This final part discusses the materials and methods of repair, in particular stressing the importance of adopting a correct technique, in so far as the state of the art exists at present. This information is necessarily somewhat less definitive than that in the first two parts of the digest, because this is an area where research is continuing; however, it is felt that guidelines of a general nature can usefully be given.

Reinforced concrete structures corrode as they age, with significant financial implications, but it is not immediately clear why some are more durable than others. This book looks at the mechanisms for corrosion and how corrosion engineering can be used for these problems to be minimized in future projects. Several different examples of reinforced concrete structures with corrosion problems are described and the various life enhancement solutions considered and applied are discussed. The book includes a chapter on the effectiveness of corrosion monitoring techniques and questions why the reality is at odds with current theory and standards. Specialist contractors, consultants and owners of corrosion damaged structures will find this an extremely useful resource. It will also be a valuable reference for students at postgraduate level.
