This book was released on 2003 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is a review of selected failures in concrete structures in which prestressing steels break in a brittle way due to stress corrosion cracking. Most cases are from the German experience over a period of about 30 years. Analysis of these failures shows that they are often due to an accumulation of causes such as poor design, errors during construction, careless detailing and, in some cases, use of unsuitable materials. This report will have achieved its purpose if it serves to avoid these past errors and encourages the development of new ways to protect, test and regulate prestressing steels. The report is complemented with comments on the properties and corrosion behaviour of different types of prestressing steels. The goal of the study is to provide objective arguments for the discussion of failures that have occurred due to corrosion induced failure of prestressing steel. In such a way the general regulation given in DIN with respect to reinforcement for robustness may eventually be proven inappropriate. The general building authority approval for prestressed hollow filler block floors already supports such an idea. It is well known that the hollow block floor industry works without any reinforcing steel. The regulations in the standards should not limit in particular the use of these types of prestressing steel (cold-formed wires, strands) which have proven not associated with any substantial failures cases reported in the last 35 years. The report reviews the historical development with respect to corrosion induced failure of prestressing steel. Concerning the circumstances of the failure examples, this review partly reflects a specific problem in Germany. Also reviewed are other known interregional examples of failure which are incorrectly attributed to the prestressed construction method. All cases considered are discussed and the failure reasons thoroughly evaluated, also with reference to the results of most recent research. Another question addressed is whether one should be concerned over corrosion induced retarded failure even when using new generation prestressing steel with correct corrosion protection. Finally a contribution to the following very important question is presented: Do the future prestressed structures possess enough safety against structural failure if they are constructed without reinforcement for robustness but otherwise comply completely with the design standards? To aid a better understanding of this short report on typical failure cases and their origins, the main conditions are set out for corrosion-induced failure of prestressing steel in technical applications. The properties of different types of prestressing steel and their application limits are given in a special section dealing with the influence of building materials on damage development. This report will be of interest to all involved in the construction process. Fundamental scientific discussion has been avoided by reference to well accredited detailed information in the technical literature.

This book was released on 2012-12-06 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete has traditionally been known as a material used widely in the construction of roads, bridges and buildings. Since cost effectiveness has always been one of the more important aspects of design, concrete, when reinforced and/or prestressed, is finding more use in other areas of application such as floating marine structures, storage tanks, nuclear vessel containments and a host of other structures. Because of the demand for concrete to operate under different loading and environmen tal conditions, increasing attention has been paid to study concrete specimens and structure behavior. A subject of major concern is how the localized segregation of the constituents in concrete would affect its global behavior. The degree of nonhomogeneity due to material property and damage. by yielding and/or cracking depends on the size scale and loading rate under consideration. Segregation or clustering of aggregates at the macroscopic level will affect specimen behavior to a larger degree than it would to a large structure such as a dam. Hence, a knowledge of concrete behavior over a wide range of scale is desired. The parameters governing micro-and macro-cracking and the techniques for evaluating and observing the damage in concrete need to be better understood. This volume is intended to be an attempt in this direction. The application of Linear Elastic Fracture Mechanics to concrete is discussed in several of the chapters.

Download or read book Corrosion of Steel in Concrete written by Luca Bertolini and published by John Wiley & Sons. This book was released on 2013-02-26 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: This report provides practical tests to identify and measure residues (e.g., rust, lubricants used in manufacturing processes, or corrosion inhibitors) on the surface of steel prestressing strands and to establish thresholds for residue types found to affect the strength of the strand's bond to concrete. Key products presented here are four test methods suitable for use in a quality assurance program for the manufacture of steel prestressing strand.
