Sandwichelemente mit UHPC‐Deckschichten und geschäumten PUR‐Kernschichten

Sandwich Elements Made of UHPC and Foamed Polyurethane Modern building envelopes are sustainable and integral building constructions, which conserve resources, hold favourable physical properties, carry loads, are modular and feature a high freedom of design. Innovative sandwich constructions with concrete facings can meet this demands. The combination of high performance concrete and corrosion resistant reinforcement made of fibre‐reinforced polymers for the outer layers in combination with foamed in pack polyurethane as core material can lead to efficient sandwich elements. The production method is tested with planar sandwich beams and sandwich plates in the first step, which additionally are the basis for sandwich elements with various cross‐sectional shapes. The test results are presented within this paper.
