This term is derived from the Greek words "rheo" (to flow) and "logos" (study). Rheology is the study of the flow (plasticity, elasticity, viscosity and fluidity) of deformable materials. In architecture, rheology is used to study the deformation of foundations. Other applications include the study of landslides in geophysics and the deformation of foundations in geo-mechanics.

The Research Center

Founded in 1887, the laboratory was the 1s in the world to specialize in cement. Since then, it has become the world's leading laboratory in the field of building materials. The L.C.R. has 15,000 m² of premises in which an international team of technicians and researchers focuses on the science of building materials.

The L.C.R. is located at L'Isle d'Abeau, near Lyon, France.
