Hybrid wall elements made of UHPC and foam concrete

Pioneering mineral composite systems for precast concrete construction

In a research project (SWD-10.08.18.7-15.20) commissioned by the Bundesinstitut für Bau-, Stadt- und Raumforschung (Federal Institute for Research on Building, Urban Affairs and Spatial Development), monolithic, load-bearing and simultaneously heat-insulating, EnEV-compliant (Energieeinsparverordnung; Energy Saving Ordinance) wall elements consisting of exterior ultra-high-performance concrete (UHPC) shells with a chemically foamed, purely mineral interior foam concrete have been developed for use as precast concrete elements. The foam concrete is based on a fine-particle UHPC mix and, unlike...
