BALCONY SOLUTION IN ULTRA HIGH PERFORMANCE CONCRETE
As the balconies in Lønneparken needed to wrap around the building’s corners, special requirements were imposed on the strength of the balcony slabs. In this context, Ultra High Performance Concrete (UHPC) proved crucial in meeting the project's structural and aesthetic demands.
UHPC is known for its exceptional strength, achieved by incorporating up to 19 million steel fibers per cubic meter. This impressive strength allows Hi-Con to produce extremely slim elements in large formats.
Lønneparken has a total of 170 balconies made from UHPC, divided into five different variants, 74 of which are large corner balconies. The balcony slabs feature integrated load-bearing beams and thicknesses as low as 50 mm, varying in width from 1.5 to 4.4 meters and in length from 3.0 to 9.5 meters. The slabs also have a cover layer of just 10-15 mm.
