L2MGC - Civil Engineering Mechanics and Materials Laboratory

L2MGC operates in the field of Civil Engineering on issues related to the optimisation of materials and the behaviour of structures and civil works. The approaches used combine both experimental studies and modelling work, from microstructural to macrostructural scales, and cover both physico-chemical and mechanical aspects and thermo-hydromechanical coupling problems.

Major scientific breakthroughs

  • Rheometry of concrete,

  • Characterisation of the near-wall flow of complex fluids (heterogeneous, draining, compacting, with setting kinetics and thixotropic),

  • Rheology-formulation-process interaction,

  • Recovery of sediments in construction materials,

  • Concrete recycling (optimisation of formulations in terms of mechanical and thermal performance and for better durability),

  • Multi-scale and multi-criteria characterisation of the resistance of materials to severe thermal stresses,
