Our research focuses on materials and structures for construction, energy and the environment. In the context of the energy transition and the natural risks related to climate change, the laboratory works in the field of innovative materials and processes, the durability and resilience of structures under complex stress, geomechanics energy and the environment. For this purpose, research is based on fundamental and / or methodological developments, combining original experimental approaches and modeling to produce knowledge that can meet the innovation needs of companies through finalized thematic projects. The scientific projects of each team are described in the corresponding section. They show the positioning of the laboratory on current topics in cooperation with major players in the field of materials, construction and energy (Saint-Gobain, LafargeHolcim, Vinci, Bouygues, Eurotunnel, Société du Grand Paris, Tunnel Euro- Alpine Lyon-Turin, EDF, Total, CEA, ANDRA, IRSN, ...). Also, many research is being developed in partnership with other IFSTTAR laboratories, especially for engineering applications.

Architectured Materials and Structures

The Architectured Materials and Structures team studies the mechanics and the durability of materials and complex or architectured structures of the civil engineering, cable networks, mixed beams, plates, slabs, pavements, heterogeneous or multilayer ... Innovative, efficient and sustainable construction concepts are also proposed and studied, including through a rigorous evaluation of environmental impacts (life cycle analysis). Prototypes are produced, including via new technologies related to digital transformation (3D printing concrete, Robot-Oriented-Design).

Geotechnics (CERMES)

The research team Geotechnics-CERMES focuses on research and teaching activities in the fields of geotechnical engineering and geomechanics. Research projects cover broad applications in civil and environmental engineering, energy production and natural hazards mitigation. Researches are based on advanced field/laboratory experimentations and theoretical/numerical analyses. They mainly concern the thermo-chemo-hydro-mechanical (THMC) behaviour of soils, rocks and cement-based materials.

Rheophysics and Porous Media

Our research mainly deals with the rheological behavior and with the flow through porous medium of complex fluids (suspensions, emulsions, pastes, foams, …) and divided media (granular material, suspensions, aerated materials, …) in the context of a multidisciplinary approach (Physics, Mechanics and Chemistry). Through basic and applied research relying on experimental, theoretical and numerical tools, we seek to advance knowledge and to develop practical solutions with applications to civil engineering, construction technology, food technology, geophysics, … The Rheophysics and Porous Media team manages NMR and MRI equipments that can measure the velocity and density fields inside flowing complex fluids and the transport and phase changes of liquid inside porous medium, a rheometry platform to measure the behavior of complex fluids, a confocal microscope and a computer cluster dedicated to molecular simulation.
