Download or read book Performance of Cement Based Materials in Aggressive Aqueous Environments written by Mark Alexander and published by Springer Science & Business Media. This book was released on 2012-12-18 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Lea s Chemistry of Cement and Concrete written by Peter Hewlett and published by Elsevier. This book was released on 2003-11-12 with total page 1092 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book External Sulphate Attack Field Aspects and Lab Tests written by Esperanza Menéndez and published by Springer Nature. This book was released on 2019-09-17 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Alkali Aggregate Reaction in Concrete written by Ian Sims and published by CRC Press. This book was released on 2017-08-01 with total page 1278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alkali-Aggregate Reaction in Concrete: A World Review is unique in providing authoritative and up to date expert information on the causes and effects of Alkali-Aggregate Reaction (AAR) in concrete structures worldwide. In 1992 a first edition entitled The Alkali-Silica Reaction in Concrete, edited by Professor Narayan Swamy, was published in a first attempt to cover this concrete problem from a global perspective, but the coverage was incomplete. This completely new edition offers a fully updated and more universal coverage of the world situation concerning AAR and includes a wealth of new evidence and research information that has accumulated in the intervening years. Although there are various textbooks offering readers sections that deal with AAR deterioration and damage to concrete, no other single book brings together the views of recognised international experts in the field, and the wealth of scattered research information that is available. It provides a ‘state of the art’ review and deals authoritatively with the mechanisms of AAR, its diagnosis and how to treat concrete affected by AAR. It is illustrated by numerous actual examples from around the world, and comprises specialist contributions provided by senior engineers and scientists from many parts of the world. The book is divided into two distinct but complementary parts. The first five chapters deal with the most recent findings concerning the mechanisms involved in the reaction, methods concerning its diagnosis, testing and evaluation, together with an appraisal of current methods used in its avoidance and in the remediation of affected concrete structures. The second part is divided into eleven chapters covering each region of the world in turn. These chapters have been written by experts with specialist knowledge of AAR in the countries involved and include an authoritative appraisal of the problem and its solution as it affects concrete structures in the region. Such an authoritative compilation of information on AAR has not been attempted previously on this scale and this work is therefore an essential source for practising and research civil engineers, consultant engineers and materials scientists, as well as aggregate and cement producers, designers and concrete suppliers, especially regarding projects outside their own region.
Download or read book Concrete in Aggressive Ground written by Building Research Establishment and published by Bre Press. This book was released on 2005 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Mitigating Sulphate Attacks in Geotechnical Engineering written by Amin Chegenizadeh and published by Nova Science Publishers. This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A magnesium sulphate attack is one of the main issues that challenge civil engineering projects, in particular in coastal, landfill, and mining areas. This phenomenon reduces the stability of the structure and causes a complete failure for the system over time. Previous studies mainly focused on investigating the effects of magnesium sulphate attacks on concrete and from a structural point of view, and only a low number of studies investigated the effects of a magnesium sulphate attack on soil from a geotechnical point of view. The investigation on the effect of a magnesium sulphate attack is an important issue, particularly for stabilised soils that have a role in maintaining the integrity of foundations, slopes, embankments, etc. Portland cement (PC) is widely used in ground improvements and geotechnical engineering projects as an additive to improve the mechanical behaviour of soil. However, PC is effective to improve the engineering characteristics of soil; it is weak when exposed to the magnesium sulphate concentration. This book investigates the behaviour of different soils when treated with PC and after exposure to magnesium sulphate contamination. Also, the effect of some abundant materials in the environment such as carbon in the mechanical behaviour of stabilised soil has been investigated. The investigations have focused on shear strength and unconfined compressive strength (UCS) as two main important characteristics of stabilised soils, and they investigate their relevant characteristics. In this study, deep investigations have been conducted to figure out the behaviour of the magnesium sulphate concentration soils. However, additional research and study is required to procure a clear understanding of the interactions of the stabilised soils with magnesium sulphate concentration.
