La surveillance des structures de génie civil constitue un enjeu majeur et fait encore l'objet de nombreuses recherches. En particulier, les problématiques de coût, de durabilité des capteurs et de fiabilité des mesures restent des aspects fondamentaux à prendre en compte pour toute nouvelle solution d'instrumentation. Les capteurs à fibre optique ...
A number of structures worldwilde are known to suffer from chemically induced expansion of the concrete. The proposed benchmark includes two sets of problems : on the material scale concrete specimens, and at the structural scale.

The use of glass powder (GP) as an alternative SCM offers a viable opportunity to partially substitute OPC, and therefore provides economic and environmental benefits. Moreover, the predominant siliceous amorphous phase provides the required component for its use as pozzolanic material. In this work, the mechanism and the products of the finely gro...
Beside lime and hydraulic binders, alkaline activation recently emerges as a possible solution for soil stabilisation. Unfortunately, soil reinforcement by alkaline activation requires additional reactive aluminosilicate sources under ambient temperature. In this study, we focus on kaolin as a simplified model of kaolin-rich soils which show limite...
The new high-speed railway link between Lyon (France) and Torino (Italy) of the Trans-European Transport Network must pass peculiar geological strata containing numerous large patches of very pure gypsum and anhydrite which will contaminate neighbouring high grade mineral layers. For the new base-tunnel with more than 57 km of length it was calcula...

Dans un monde qui s'oriente de plus en plus vers le développement durable, les matériaux alcali-activés (AAM) à base de co-produits industriels comme le laitier granulé de hauts fourneaux moulu (GGBFS), sont apparus comme étant de nouveaux types de liants pour diverses applications dans le domaine du Génie Civil. Les AAM sont d'une grande importanc...
