A Fiber-Reinforced Architectural Concrete for the Newly Designed Fa?ade of the Poseidon Building in Frankfurt am Main

摘要

In the course of revitalizing the Poseidon Building in Frankfurt, an energetically optimized fa?ade, made of architectural concrete was developed. The development of a fiber-reinforced architectural concrete had to consider the necessary mechanical strength, design technology and surface quality. The fiber-reinforced architectural concrete has a compressive strength of 104.1 MPa and a 3-point bending tensile strength of 19.5 MPa. Beyond that, it was ensured that the fiber-reinforced high-performance concrete had a high durability, which has been shown by the capillary suction of de-icing solution and freeze thaw test with a weathering of abrasion of 113 g/m2 after 28 freeze-thaw cycles and a mean water penetration depth of 11 mm.
