LERM’s expertise is based on the fundamental knowledge of hydraulic binders. This knowledge progressively extended to concrete and its pathologies in the sector of building and civil engineering infrastructures. Then, it developed to stone and its special features related to ageing in the field of historic monuments. Our knowledge of binders and concrete naturally led us to develop a new point: recycling waste or industrial by-products in the sector of building materials.

Building materials

• Concrete, cement, lime, plaster…
• Additions, admixtures
