Book Description
Chemical admixtures are used to modify the properties and behaviour of fresh and hardened concrete. They enable more economic construction and the achievement of special properties such as high strength or durability. This book presents new research information from an International RILEM Symposium on six main topics: workability, setting, strength, durability, other properties and technology.

Book Description
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.

Book Description
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.
