Available in PDF, EPUB and Kindle. Book excerpt: As critical concrete infrastructure deteriorates, engineers need efficient and reliable techniques to appraise the causes and the extent of deterioration, to evaluate the structural consequences and to select effective management protocols and rehabilitation strategies. This book looks at deterioration caused by internal swelling reaction (ISR) mechanisms in concrete, such as alkali-aggregate reaction, delayed ettringite formation and freeze-thaw cycles. The book provides accessible and comprehensive coverage of recent work and developments on the most common ISR mechanisms leading to induced expansion and deterioration. It addresses the implications of ISR on different scales (micro, meso and macro), outlines qualitative and quantitative techniques to assess the condition of affected concrete and introduces the multi-level assessment protocol, using advanced microscopic and mechanical techniques, particularly the stiffness damage test and damage rating index, as a reliable approach to appraise ISR-affected infrastructure. Also included is a detailed case study of the Robert-Bourassa Charest Overpass in Quebec. Internal Swelling Reactions in Concrete: Mechanisms and Condition Assessment is primarily intended for undergraduate and graduate students, as well as academics interested in the field of concrete durability and condition assessment of concrete. It will also be of interest to engineers and infrastructure owners dealing with ISR-related problems.

Book excerpt: In the second part of the book, the chemical, the mineralogical composition and the microfabrics of concretes and related materials are discussed. An illustrated guide to the features that can be observed and identified using a petrological microscope is given. There is an extensive review of the defects, deterioration and failures which can occur in concrete together with the observations and petrographic evidence relating to them. Extensive use has been made of illustrative examples in colour which together with appropriate discussion will assist the engineer as well as both the trainee and experienced petrographer in understanding the nature of the evidence which is basic to petrographic analysis. An extensive glossary of optical and other properties of minerals found in concretes completes this practical handbook.

This book was released on 2004 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Face à la demande réelle d'une maintenance des ouvrages d'art en béton affectés par la réaction d'alcali-silice, ces travaux de thèse présentent, d'une part, une modélisation mécanique du gonflement du matériau induit par la formation des produits de réaction alcali-silice et, d'autre part, une méthode d'expertise des structures réellement touchées. La modélisation du comportement du matériau nécessite de préciser deux aspects fondamentaux : la cinétique de formation des produits et la réponse mécanique à cette formation interne. Issus de la thermodynamique du béton en tant que système chimico-mécanique, l'avancement chimique de réaction et la réponse mécanique se trouvent dans la même description. Sur le plan chimique, l'expansion des produits de réaction - que nous désignerons sous le terme " gel " - est d'abord représentée par l'avancement de la réaction de formation d'un gel simple, et puis divisée en deux sous-processus : la formation du gel et son vieillissement en fonction des conditions hydriques. Quant à la réponse mécanique du matériau, le béton est premièrement supposé élastique et puis élastoplastique. Les deux aspects - chimiques et mécaniques - étant traités, on aborde alors l'expertise numérique des structures affectées, dans le contexte du traitement des ouvrages d'art concernés dont proviennent les données nécessaires à l'analyse. En traitant ces données au niveau d'une structure ainsi qu'au niveau d'une carotte extraite, le calibrage des modèles chimico-mécaniques est formulé sous la forme d'un problème inverse, qui est scindé en deux sous-problèmes vis-à-vis des données analysées. Le calibrage est achevé par la proposition d'un algorithme et de son critère de convergence. Une méthode numérique d'expertise est ainsi disponible, représentant une partie essentielle de la méthodologie globale de traitement des structures. Cette méthode est appliquée à des cas réels d'ouvrages affectés : un pylône en béton armé d'un pont suspendu en France et une pile en béton armé d'un pont métallique en Afrique équatoriale.

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.
