Building the Future on Lessons of Historic Reinforced Concrete

This contribution presents the way the construction material reinforced concrete was introduced at the beginning of the 20th century, from both the technical (Hennebique system) and the philosophical points of view. The philosophy underlying the use of this material is evident in the theories on finding a language of form corresponding to tectonics, and its dialogue with timber, formulated by certain notable practicing architects of the time across Europe. Not to be neglected are aspects relating to the conservation of material and to interventions carried out over time. In Modernist times, this meant a change from the artistic expression of Art Nouveau. Today, it means technical adaptation. The paper addresses thus sustainability of intervention versus conservation.
