Magnesium silicate hydrate (M-S-H) characterization : temperature, calcium, aluminium and alkali
2017
The various options to store radioactive wastes in deep geological strata considered in France or Switzerland include the use of large volumes of cementitious materials for infrastructure in contact with argillaceous rocks. So-called low-pH binders were developed to minimize disruption to the surrounding rock by the alkaline plume. Studies conducted on the interaction zone between concrete and clay systematically highlighted the formation of magnesium silicate phases including magnesium silicate hydrate (M-S-H) at the interfaces, which can presently be modeled only partially due to incomplete thermodynamic data. The purpose of this study was to characterize these phases in temperature, alum…

Mobilités étudiantes et territoires universitaires :vers une uniformisation des pratiques ?
2005
Since French Society enters the so-called “Economy of knowledge”, migrations of young people, especially these concerning students, are of most interests. Despite the fact that it could help to understand University as a system and ways regions can evolve, the study of students' migrations was not yet done. A set of results highlights first the main role of French capital region. It shows also main changes in migrations of students following vocational training in University. At least, it reveals that architectures of students' migrations look like these of migrations of the whole French population.
