The Technical University of Dresden is constructing the world's first concrete building with carbon fiber reinforcement. The experimental building made of carbon concrete will present the possibilities of the new composite material to the public in the middle of Dresden.

"Cube" is the name of the world's first building made of carbon concrete, which the Technical University of Dresden is building in the Saxon capital.

Reinforced concrete is the most important building material in the world today. But in times of climate change, it is also increasingly in criticism. The concrete layer, which is required to protect the steel from corrosion, is too thick, and the consumption of CO2-intensive cement is too high. If the Technical University of Dresden (TU Dresden) has its way, carbon concrete, i.e. the composite material made of rustproof carbon fiber reinforcement and high-performance concrete, should overtake conventional reinforced concrete in the future. The change in material to carbon concrete would reduce the energy requirement and CO2 emissions in the manufacture and repair of buildings by up to half and save valuable resources, writes the TU Dresden.

The university now wants to convey the results of its carbon concrete research offensive to a broader public in concrete terms. For this purpose, the TU Dresden is building the world's first building made of carbon concrete. These days, the Saxon state capital gave the green light and granted the building permit. By the end of 2020, a building that is unusual in its construction and futuristic in appearance will be built on Einsteinstrasse: a 220 square meter experimental building that will also serve as a test stand. The building originally planned as a cube with the project name “Cube” has received additional architectural momentum. Two twist elements arranged symmetrically opposite each other will form the side and top of the room at the same time and illustrate the extraordinary range of applications for carbon concrete construction. The so-called box will also make it clear that conventional building structures according to the state of the art can already be built with carbon concrete. The flagship project of the “C³ - Carbon Concrete Composite” project financed by the German Federal Ministry of Education and Research thus bundles all the results that have been intensively researched in this project since 2014.

Invented in Dresden, built in Dresden: An experimental building can now be built in the Südvorstadt. That's so special about it. The Cube is the world's first carbon concrete house. It is being built in Dresden.

The world's first house made of so-called carbon concrete is allowed to be built. By the end of 2020, a futuristic looking building will be built on an area between Fritz-Foerster-Platz, Zelleschem Weg and Einsteinstraße - both in terms of construction and appearance. The city administration has now issued the building permit so that work can begin, the Technical University announced on Friday.

By using carbon concrete, a good 50 percent less concrete could be used than usual. This is made possible by the structure of the material. At its heart are textile carbon fibers, which are processed into a lattice using a special knitting and coating process. That is the core of the concrete slab. Unlike steel, carbon does not rust. It does not have to be protected by thick layers of concrete, as is the case with reinforced concrete. Half a centimeter on either side of the grille is enough. Result: only half of the concrete is required for production. That also makes carbon concrete significantly lighter.
