Dresden University of Technology 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 constructing in the capital of Saxony.


Reinforced concrete is the most important building material in the world today. In times of climate change, however, it is coming under increasing criticism. The concrete layer that is supposed 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 stainless carbon fiber reinforcement and high-performance concrete, will replace conventional reinforced concrete in the future. The change of material to carbon concrete would reduce energy requirements and CO2 emissions in the production and repair of buildings by up to half and conserve valuable resources, writes the TU Dresden.


The university now wants to communicate the results of its carbon concrete research in concrete terms to a wider public. To this end, the TU Dresden is constructing the world's first building made of carbon concrete. The Saxon state capital recently gave the green light and issued the building permit. By the end of 2020, an unusual and futuristic-looking building is to be erected on Einsteinstrasse: a 220-square-meter experimental building that will also serve as a test unit. Originally planned as a cube, the building with the project name "Cube" will be given additional architectural momentum: two symmetrically opposing, twisted elements will simultaneously form the side and the top of the room and illustrate the extraordinary application possibilities of the carbon concrete construction method. The so-called box will also make it clear that carbon concrete can also be used to build conventional state-of-the-art structures. The lighthouse project of the "C³ - Carbon Concrete Composite" project funded by the German Federal Ministry of Education and Research thus brings together 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 Südvorstadt. The special thing about it. The Cube is the first carbon concrete building in the world. It is being built in Dresden.

The world's first house made of so-called carbon concrete may be built. By the end of 2020, a futuristic-looking building is to be erected on an area between Fritz-Foerster-Platz, Zellescher Weg and Einsteinstraße - both structurally and visually. The city council 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 than usual could be used. This is made possible by the structure of the material. At its heart are textile carbon fibers, which are processed into a grid in a special knitting and coating process. This is the core of the concrete slab. Unlike steel, carbon does not rust. It does not need to be protected by thick layers of concrete, as is the case with reinforced steel concrete. Half a centimeter on each side of the grid is sufficient. As a result, only half of the concrete is needed for production. This also makes the carbon concrete significantly lighter.
