Corrosion of Steel in Concrete


Book Description

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.




Transport Properties of Concrete


Book Description

Transport Properties of Concrete: Modelling the Durability of Structures, Second Edition, covers how to measure transport properties and use the results to model performance. The transport properties of concrete and measurements of the ability of ions and fluids to move through the material. These properties largely determine the durability of concrete and of steel embedded within it, as well as the effectiveness of structures such as waste containment barriers. The book provides a comprehensive examination of the subject and will be of use to all concerned with the durability and effectiveness of concrete structures. - Includes a new chapter on modelling the durability of concrete structures showing how both diffusion and pressure driven flow should be included - Covers the problems that occur when carrying out transport tests on concrete incorporating both traditional and newer cement replacements - Shows how properties such as permeabilty which are needed for modelling may be derived from in situ tests on structures




Resistance of Concrete to Chloride Ingress


Book Description

Chloride ingress in reinforced concrete induces corrosion and consequent spilling and structural weakness, and it occurs world-wide and imposes an enormous cost. Yet it can be resisted by using test methods and relevant models for service life prediction.Resistance of Concrete to Chloride Ingress sets out current understanding of chloride transport

Integral Waterproofing of Concrete Structures


Book Description

Integral Waterproofing of Concrete Structures demonstrates how integral waterproofing technologies can solve concrete durability problems based on performance and characterization experimental results. This book first establishes a background about concrete structures and porosity linked with concrete hydration, then goes on to consider concrete durability problems from the perspective of water penetration including damages from freeze-thaw cycles, alkali silica reactions, and chloride ion penetration. The mechanisms, applications, performances, and limitations of waterproofing technologies including coatings and integral systems are compared. The book also showcases all application methods of crystallization waterproofing materials, including material spray on cured concrete and on fresh concrete, and their addition to concrete mix designs as enhancers or admixtures. Pore-blocking and lining waterproofing systems including silicate-based and hygroscopic kinds, and other waterproofing materials are also discussed. - Includes various, advanced, recent technologies in the field of waterproofing - Presents and describes enhanced concrete characteristics and modified structures within the context of material engineering - Summarizes the characteristics of waterproofing systems obtained from experimental results




Transport and Interactions of Chlorides in Cement-based Materials


Book Description

Chloride-induced corrosion is the most important durability issue of reinforced concrete structures, and the prediction and prevention of chloride-induced corrosion has attracted considerable interest all over the world. Given that chloride penetrates through the concrete cover, the issues concerning its transport are crucial. These include testing methods, prediction, and the prevention of ingress. During the transport process, physical and chemical interaction occurs between chloride and cement hydrates, which in turn affects the further transport, so the transport of chloride and these interactions are closely related and underpin our understanding of chloride-induced corrosion in RC structures. This book provides in-depth discussion of chloride transport and its interaction in cement-based materials, and reviews and summarizes the state of the art. The mechanisms and testing methods for chloride transport, chemical interactions of chloride with cement hydrates, chloride binding isotherms, measurement of penetration depths, factors affecting chloride transport, and modeling of chloride transport are discussed in detail. This book serves as a reference for researchers or engineer, and a textbook for graduate students.
