Materials Science of Concrete by Jacques Marchand,Jan P. Skalny Pdf

The 18 papers grapple with new problems and old ones that remain unresolved concerning sulfate attack on concrete, not considered one of the most prevalent mechanisms of concrete deterioration, but one that has received much attention lately because of costly litigation against manufacturers, developers, and others. The topics include the role of ettringite in external sulfate attack, microstructural alterations in permeable concrete, assessing damage and predicting service life of venerable concrete, a marine environment, and the adequacy of standards.

Performance of Cement-Based Materials in Aggressive Aqueous Environments by Mark Alexander,Alexandra Bertron,Nele De Belie Pdf

Concrete and cement-based materials must operate in increasingly aggressive aqueous environments, which may be either natural or industrial. These materials may suffer degradation in which ion addition and/or ion exchange reactions occur, leading to a breakdown of the matrix microstructure and consequent weakening. Sometimes this degradation can be extremely rapid and serious such as in acidic environments, while in other cases degradation occurs over long periods. Consequences of material failure are usually severe – adversely affecting the health and well-being of human communities and disturbing ecological balances. There are also large direct costs of maintaining and replacing deteriorated infrastructure and indirect costs from loss of production during maintenance work, which place a great burden on society. The focus of this book is on addressing issues concerning performance of cement-based materials in aggressive aqueous environments , by way of this State-of-the-Art Report. The book represents the work of many well-known and respected authors who contributed chapters or parts of chapters. Four main themes were addressed: I. Nature and kinetics of degradation and deterioration mechanisms of cement-based materials in aggressive aqueous environments, II. Modelling of deterioration in such environments, III. Test methods to assess performance of cement-based materials in such environments, and which can be used to characterise and rate relative performance and inform long term predictions, IV. Engineering implications and consequences of deterioration in aggressive aqueous environments, and engineering approaches to the problem.

External Sulphate Attack – Field Aspects and Lab Tests by Esperanza Menéndez,Véronique Baroghel-Bouny Pdf

This volume gathers contributions from the final workshop of the RILEM TC-251-SRT "Sulfate Resistance Testing" on External Sulfate Attack (TESA 2018), held on May 24-25, 2018 at IETcc-CSIC, Madrid, Spain. One of the Technical Committee’s main events, it addressed various aspects of external sulfate attack in concrete structures and test methods. The workshop promoted technical discussions and debates on ideas on these topics, with a focus on evaluating the resistance of concrete exposed to ESA. It also provided a forum for participants from around the globe to share their experiences and research on concrete structures affected by external sulfate attack and on test methods. The book discusses the latest advances in research related to ESA and new developments in test methods, and features real-world case studies of concrete structures affected by external sulfate attack in various countries. It also presents new studies linking field cases and lab tests, including 12 contributions on 3 main themes: mechanisms of alteration in external sulfate attack; field aspects of external sulfate attack; and testing to evaluate the resistance of concrete to external sulfate attack.

Lea's Chemistry of Cement and Concrete by Peter Hewlett Pdf

Lea's Chemistry of Cement and Concrete deals with the chemical and physical properties of cements and concretes and their relation to the practical problems that arise in manufacture and use. As such it is addressed not only to the chemist and those concerned with the science and technology of silicate materials, but also to those interested in the use of concrete in building and civil engineering construction. Much attention is given to the suitability of materials, to the conditions under which concrete can excel and those where it may deteriorate and to the precautionary or remedial measures that can be adopted. First published in 1935, this is the fourth edition and the first to appear since the death of Sir Frederick Lea, the original author. Over the life of the first three editions, this book has become the authority on its subject. The fourth edition is edited by Professor Peter C. Hewlett, Director of the British Board of Agrement and visiting Industrial Professor in the Department of Civil Engineering at the University of Dundee. Professor Hewlett has brought together a distinguished body of international contributors to produce an edition which is a worthy successor to the previous editions.

Sulfate-resistant Concrete: Literature Review by O. Lynn England Pdf

A limited review of technical literature was made to determine the present state of knowledge concerning: (a) nature and mechaniem of sulfate attack on concrete; (b) methods of minimizing or preventing sulfate attack; and (c) methods of guarding or restoring existing structures affected by sulfate attack. The information obtained showed that, generally, the degree of sulfate attack on a concrete structure is dependent upon: (a) type of cement used; (b quality of concrete with regard to sulfate resistance; (c) local conditions (sulfate concentration in soil and ground water); and (d) surface protection. Before the structure is built, local conditions should be studied to determine the need for using Type II or V, or special cements, or for addition of pozzolans. In sulfate attack is expected, the quality of the concrete is of paramount importance. Surface coatings may be used as a precaution but cannot be substituted for good-quality concrete. After the structure is in place, surface coatings and adequate drainage are the only means of protecting the concrete from sulfate attack. (Author).

Concrete in Aggressive Ground by Building Research Establishment Pdf

This BRE Special Digest provides practical guidance on specifying concrete for use in natural ground and in brownfield locations. The procedures for ground assessment and concrete specification cover the fairly common occurrence of sulfates, sulfides and acids and also the more rarely occurring aggressive carbon dioxide found in some ground and surface waters, which affects concrete foundations and sub-structures. This edition has been revised to reflect thinking and changes to British Standards. It introduces the phenomenon of chemical attack of concrete in the ground, describes modes of chemical attack and discusses the mechanisms of the principal types, including sulfate and acid attack, and the action of aggressive carbon dioxide. It then gives guidance on assessing the chemical aggressiveness of the ground, and recommendations for specifying concrete for general cast-in-situ use in the ground. It also gives recommendations for specifying surface carbonated precast concrete for general use in the ground, and includes design guides for specification of specific precast concrete products, including pipeline systems, box culverts and segmental linings for tunnels and shafts. The guidance applies to both buildings and civil engineering construction.
