Available in PDF, EPUB and Kindle. Book excerpt: À l'état durci, le béton est un matériau poreux complexe. Ses propriétés d'usage (performances mécaniques ou thermiques, durabilité…) sont liées à sa structure poreuse qui elle-même dépend de l'arrangement des grains à l'état frais. Étudiant les propriétés des matériaux granulaires et celles de leurs mélanges, cet ouvrage propose différents outils permettant au formulateur de concevoir des bétons de façon innovante. Afin de décrire les méthodes de caractérisation des matériaux, il analyse les propriétés physiques sur lesquelles elles reposent et établit ainsi leurs limites. Il développe également les notions de porosité et de surface spécifique et présente les propriétés de transport des bétons (diffusion et perméation). Chaque chapitre se termine par plusieurs exercices permettant d'assimiler les connaissances théoriques présentées et de les appliquer à des problèmes concrets de génie civil.

This book was released on 2013-05-01 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce livre est un des tout premiers « si non le premier » exclusivement dédié au domaine des bétons de végétaux. Nous nous employons au fur et à mesure des chapitres de décrire l’intérêt de l’usage de tels matériaux, de décliner les nombreuses propriétés multiphysiques et enfin d’illustrer les modes de fabrication et de mise en œuvre. Le livre se focalise principalement sur l’exemple du béton de chanvre. Ce matériau est aujourd’hui très largement utilisé dans l’industrie de la maison individuelle. Le confort thermique, hygrothermique et acoustique est induit par la structure exceptionnelle du matériau dans le sens où elle associe porosité, légèreté et inertie. Le comportement mécanique n’est pas en reste, une grande ductilité et des propriétés loin des standards habituels sont précisées dans cet ouvrage. Par ailleurs, l’Analyse de cycle de vie dont la plus grande partie du volume est d’origine végétale fait ressortir un bilan qui lui est très favorable.

Download or read book Cutoffs for Dams written by CIGB ICOLD and published by CRC Press. This book was released on 2018-12-07 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: ICOLD Bulletin 150, Cutoffs for Dams, discusses foundation treatment methods using cutoff-type barriers. High emphasis is given to alluvial deposits throughout this document; however, different materials may require cutoff. The construction of cutoffs has made significant advances mainly through the development of more powerful machinery for drilling and excavation, but also through the introduction of new concepts and techniques, such as jet grouting and deep soil mixing. The following types of cutoffs are presented in this Bulletin: - Diaphragm walls - Vib walls - Pile walls - Superimposed concreted galleries - Jet grouting - Deep mixing These methods are described, and the practical application of each method is illustrated by selected case histories. These case histories also demonstrate how certain difficulties specific to a particular dam site have been dealt with. The performance of cutoffs should be monitored so that their efficiency in reducing flow and piezometric head can be evaluated. Piezometers installed in the foundation upstream and downstream of the cutoff are needed to meet this objective.

Download or read book Roller Compacted Concrete Dams written by CIGB ICOLD and published by CRC Press. This book was released on 2020-12-22 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: ICOLD Bulletin 177 ‘Roller-Compacted Concrete Dams’ presents the state-of-the-art on roller-compacted concrete technology for dams, incorporating the advances of the RCC technology for dams over the last 15 years since the previous Bulletin on the topic was released in 2003. Hence, the present ICOLD Bulletin 177 supersedes ICOLD Bulletin 126 (‘Roller-compacted concrete dams - State of the art and case histories’, published in 2003) and ICOLD Bulletin 75 (‘Roller-Compacted Concrete for Gravity Dams’ published in 1989). While roller-compacted concrete technology could have still been considered a new technology in 2003, it is now true to say that construction by roller-compaction has become the standard approach for large concrete gravity dams. This Bulletin addresses all aspects of the planning, design, construction and performance of RCC in dams. Mixture proportioning and quality control are discussed and a comprehensive listing of references is included. Many aspects of RCC in dams have become better understood since the publication of Bulletin No 126 and the present Bulletin contains less information on the particular approaches applied in different countries, but includes more comprehensive information particularly in relation to design, mixture proportioning and construction. With greater understanding, it has further been possible to highlight more definitively the requirements of successful RCC dams, as well as the pitfalls and difficulties that can be associated with RCC dam design and construction. Le Bulletin CIGB 177, intitulé « Barrages en Béton Compacté au Rouleau » présente les dernières avancées en matière de technologie du béton compacté au rouleau pour les barrages intégrant les progrès de la technologie BCR pour les barrages au cours des 15 dernières années, depuis que le dernier bulletin sur le sujet a été publié en 2003. Par conséquent, le bulletin 177 remplace le bulletin 126 (« Barrages en béton compacté au rouleau - Technique actuelle et exemples », publié en 2003) et le bulletin 75 (« Béton compacté au rouleau pour barrages-poids - Technique actuelle » publié en 1989). Alors que la technologie du BCR pourrait encore être considérée comme une nouvelle technologie en 2003, il est maintenant vrai de dire que la construction par le compactage par rouleaux est devenue l'approche standard pour les grands barrage-poids en béton. Ce bulletin aborde tous les aspects de la planification, de la conception, de la construction et de la performance du BCR dans les barrages. Le dosage du mélange et le contrôle de la qualité sont discutés et une liste exhaustive des références est incluse. De nombreux aspects du BCR dans les barrages sont mieux compris depuis la publication du Bulletin no 126. Le présent bulletin contient moins d'informations sur les approches particulières appliquées dans différents pays, mais comprend des informations plus complètes notamment en ce qui concerne la conception, le dosage du mélange et la construction. Avec une plus grande compréhension, il a été possible de mettre en évidence les exigences des barrages en BCR réussis, ainsi que les pièges et les difficultés qui peuvent être associés à la conception et la construction du barrage en BCR.

Download or read book Freeze Thaw Durability of Concrete written by J. Marchand and published by CRC Press. This book was released on 2004-03-01 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete durability in climates where freezing and thawing occurs is a continuing problem. It is particularly acute for highway and bridge structures, where de-icing salts are used to combat the effects of frost, snow and ice. These salts can cause damage to concrete and accelerate corrosion of reinforcements. This book presents the latest international research on this area, with contributions from North America and Europe which were presented at an international RILEM workshop.

Download or read book Production Methods and Workability of Concrete written by P.J.M. Bartos and published by CRC Press. This book was released on 2004-06-02 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: Practical production of ordinary and special, high performance concretes and their behaviour and properties when fresh are the main themes of this book. It derives from the International RILEM Conference held in Paisley, Scotland in June 1996, and represents the culmination of the work of two RILEM Technical Committees (145 WSM Workability of Special Mixes, and 150 ECM Efficiency of Concrete Mixers). Very significant advances have been made recently in the development of concrete with outstanding properties. Such advances in research must be matched by progress in the technology of concrete production. This book focuses on production methods and on workability and handling, two fundamental and closely linked stages of the concrete construction process. It has a strongly practical emphasis, with many contributions showing how to build effectively using the many high performance concretes which have progressed from research into construction in recent years. The main themes covered are: production mixers and mixing processes; production methods; sprayed and very dry precasting mixes; fibre reinforced concrete; flowing and superfluid mixes; rheology; test methods; mix design and models; special cements and concretes.

This book was released on 2022-05-04 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete is a material used widely in building and construction applications worldwide; hence, it plays a significant role in the global construction sector. Cement is a major component of concrete and is used in construction applications, either on its own or as a composite with other materials, to improve workability, durability, strength, weight, and shrinkage. However, cement and concrete production and use have adverse environmental effects. Thus, great efforts have been made to produce eco-friendly concrete. This book examines several aspects of sustainable concrete technologies, including new forms of concrete as well as different approaches for creating sustainable cement.
