Project information

Special Feature

of the project

The curtain wall of the technical faculty consists of seven CRC panels made of a special white cement with fibre reinforcement, giving the building a dynamic appearance. At the same time, the curtain wall protects against 50% of solar radiation and provides natural ventilation and glare protection. 65% of the facade consists of holes.

Architectural Masterpiece with UHPC

The choice of fibres is crucial

In order to be able to produce extremely slender or highly perforated structures such as the facade elements of the Southern Danish University in Odense, the UHPC concrete must ensure high stiffness combined with ductility. This is achieved by adding steel microfibres. The use of stainless steel fibres enables durable highly aesthetic surfaces that can withstand stressful environmental conditions. In addition, polypropylene fibres can be used in UHPC components to increase the fire resistance of the ultra-high strength concrete.

A whole series of parameters determine the material properties of UHPC: aggregate, binder and their packing density, fibre geometry, fibre content and steel grade. As a rule, steel fibres are the most economical solution for HPC and UHPC projects. However, depending on the requirements of the UHPC components, a mixture of different fibre types and, in many cases, a combination reinforcement of prestressed and / or slack reinforcement may also be suitable.

Thanks to the extreme rigidity and high ductility of fibre-reinforced concrete, exceptionally thin UHPC components with an extremely low dead weight can be realized. With the appropriate fibres or fibre mixtures, you can also achieve highly dense and wear-resistant surfaces, up to 20 times the resistance to shear deformations and to short-term dynamic extraordinary impacts such as explosion compared to conventional concrete, as well as increased stiffness of the concrete even in the cracked state. The combination of these advantages makes architectural masterpieces possible and ensures the safety and durability of new and existing buildings.

The perfect basis for

UHPC constructions

Our portfolio of fibre types, fibre geometries and material specifications offers ideal conditions for the high requirements in the field of high-strength and ultra-high-strength concretes. We advise you on the selection of suitable fibres or fibre blends. If desired, we can also undertake the hardened concrete testing of the selected material in cooperation with our engineering partner SCE. Beyond the desired concrete properties, we thus guarantee a reliable project result.

Thanks to its outstanding material properties, ultra-high performance concrete (UHPC) enables load-bearing structures and architectural works of art that far surpass conventional concrete construction in terms of lightness and filigree. Structures realized with UHPC can be so fascinating in their form that one might mistake what one sees for an optical illusion. The exceptionally thin, yet extremely strong UHPC components also set new standards in terms of durability. Reinforced with special microsteel fibres, the concrete can be the basis for extremely perforated facade elements, wide-spanning roof structures or column-free filigree bridges. The material also offers many possibilities for refurbishing and reinforcing damaged concrete and steel components. For example, ultra-high-strength concrete roadways help to increase the service life of our bridges - while shortening planning and construction times
