The Cube
The CUBE in Dresden, the world's first carbon concrete building, was constructed entirely without steel reinforcement.

The CUBE consists of two parts – the TWIST and the BOX. It is an experimental building and at the same time a vehicle for researching the long-term suitability of carbon concrete in terms of structural design, structural engineering and building physics.

Schöck Combar is used as connection reinforcement in the foundation of the BOX, and absorbs the load of the external walls.

The energy efficiency of the roof is ensured by 14 centimetres of thermal insulation and Schöck Isolink façade anchors, which minimise thermal bridges.

To use Schöck Combar to reinforce walls at the corners, the required bending radii had to be adapted to the requirements of the slender wall structures.

The structure of the composite walls is clearly visible here. The cavity is filled on site with in-situ concrete.

Edge beams were formed in the roof area of the TWIST. Schöck Combar reinforcement cages also guarantee reliable load transfer here.

Schöck Combar is the only fibre composite material on the market, which has been approved by the building authorities since 2008. Straight and curved bars are available, offering flexibility in terms of component geometries – as in the case of The CUBE Dresden.

Schöck Isolink Type C is the façade fastener made of glass fibre composite material and the energy-efficient alternative to conventional stainless steel solutions for connecting the concrete shells of core-insulated sandwich and element walls.

The world's first building made of carbon concrete was inaugurated in Dresden in September 2022. It consists of a futuristic curved roof construction and a simple cube. The aim of the initiator, the Institute for Solid Construction at TU Dresden, is to research the long-term suitability of carbon concrete in terms of structural design, statics and building physics. The two completely different geometric elements of the building demonstrate the range of construction forms that can be realised with non-metallic reinforcement.
Thanks to the different bar shapes, Combar® in bar and stirrup form was used in the edge beams of the roof structure - this was the only way to secure the load-bearing structure of the unusual building geometry.
The load-bearing and weather shells were connected with Isolink® type C. With the non-metallic materials and innovative insulation, a wall structure of just 27 centimetres could be realised - a thickness of 44 centimetres is usual in reinforced concrete construction.
