Concrete Lightweight Ceiling

EIGNER Betonmanufaktur GmbH & Co. KG

Concrete Lightweight Ceiling uses 3D-printed concrete segments as integrated formwork to revive an almost forgotten method of reinforced concrete ribbed ceilings. The hollow bodies result in material savings of 40% concrete and 30% less reinforcing steel. In combination with a CO2-optimised R-concrete formula, a reduction of CO2 is achieved compared to the originally planned reinforced concrete flat ceiling. Concrete is only used where it is needed.
