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.
