Status 2016

Concrete gives shape to the world we live in. The steel bars embedded in the concrete up to now reinforce the material and give it stability. Steel reinforced concrete is resource intensive, environmentally stressing, heavy and, moreover, susceptible to corrosion. In fact, we are faced with the consequences of corrosion damage, including deteriorated bridges and roads, every day. The thought of not being stuck in traffic jams anymore seems tempting, but unrealistic. However, if Manfred Curbach, Chokri Cherif and Peter Offermann had their way, all of the above could be changed soon. The three scientists hope to be able to replace approximately 20% of steel reinforced concrete with carbon concrete in the near future. But what exactly is carbon concrete, and what makes it so special? The innovative material is a composite made of high-performance concrete and carbon reinforcement. The revolution is in the carbon fibre, which produce a light, flexible and durable material. Each yarn is composed of up to fifty thousand of these extremely fine carbon fibres. A textile machine then processes the yarns into a fabric covered with a stabilising coating. Moreover, for an optimal load-efficiency in the concrete the fibres can be arranged according to the stress distribution. The result is a corrosion-resistant and resource-efficient alternative to steel reinforced concrete.

The Dresden scientists have been working on this fascinating material since the 1990s. The fundamental knowledge about carbon concrete is based on research about textile reinforced concrete, carried out between 1999 and 2011 in two collaborative research centres of the Deutsche Forschungsgemeinschaft DFG in Dresden and Aachen. The scientific knowledge gained by this research was gradually put into practice. The founding of the organisations Deutsches Zentrum Textilbeton, Tudalit e.V., TUDATEX GmbH and CarboCon GmbH is yet another result of their hard work. Along the process chain – from the basic material to the finished building component – the practical implementation process already began and is being continued since 2014 by the largest German construction research project "C³ - Carbon Concrete Composite". This project, financed by the Federal Ministry of Education and Research, is managed by Professor Manfred Curbach and, under the lead management of the Technische Universität Dresden, is making significant advances in the research of carbon concrete. More than 140 companies are currently working together in order to successfully bring the material on the market.

Carbon concrete is light, corrosion-resistant and flexible. Therefore, any field in need of resource and energy efficient, durable, space-saving and multifunctional construction methods is a potential market.

Carbon concrete can be utilised in two areas: structure maintenance (tunnels, bridges, residential and industrial buildings, concrete masts) and new constructions; in short, in all fields, where the main focus lies on reducing the mass of construction components, and hence the structure's dead load. For façade panels or balcony floor boards for instance, the costs for material, transport and fitting, as well as the substructure, fastening and support structure, can be drastically reduced. Due to lightweight building components the level of factory prefabrication can be increased, resulting in lower costs and higher quality.

Numerous strengthened buildings and new constructions demonstrate the practicality and high resource-efficiency of carbon concrete in an impressive and convincing manner.

Economical: Carbon concrete reduces costs and saves material
Building with carbon reinforced concrete creates new values. New structures with a significantly extended utilisation period are proof of this. At the same time, carbon concrete sustains existing values by the chance of reinforcing old buildings with very thin layers of concrete, enabling their continued use for a prolonged period of time. Carbon concrete not only saves valuable resources, but also allows us to reduce the total cost of construction. During the tender process for the strengthening of the historical railway bridge in Naila at the beginning of 2016, carbon concrete was chosen over steel reinforced concrete because it was 10% cheaper. Moreover, using carbon concrete for the structural retrofitting saved approximately 80% of the material.

The important thing is that as far as the technical efficiency is concerned, carbon and steel are equal in terms of price, although the kilogramme-prices may give a different impression. 1 kilogramme of steel costs appr. 1 euro, whereas a kilogramme of carbon costs appr.16 euros, respectively. However, the density of carbon is four times lower than that of steel, and its strength is six times as high. Consequently, for 16 times the price you get 24 times the technical efficiency.

For instance, façade panels or reinforcement layers made of carbon concrete are approximately only two centimetres thick, whereas if made of steel reinforced concrete, they would be eight centimetres thick. As such, the amount of material that has to be manufactured, transported, built in and fixed is reduced by 75%. Moreover, the significantly longer period of use plays an important role: whilst structures made of steel reinforced concrete have to be retrofitted every 40 to 80 years due to corrosion damage, carbon concrete is considered to have a service life of up to 200 years or more.

Efficient: Using carbon concrete reduces CO2 emissions and saves valuable resources
The building industry is one of the most important branches of the German economy. Its level of innovation will have a significant influence on whether Germany succeeds in fulfilling its climate goals - the reduction of CO2 emissions, energy saving and resource conservation. With the exception of water, concrete is the most-used raw material, with approximately 5 billion m³. Concrete is composed of cement, sand, gravel and water. 1.6 billion tonnes of cement, 10 billion tonnes of sand and gravel aggregate, and one billion tonnes of water are used in the development and retrofitting of buildings and bridges every year. Thereby, every tonne of cement generates over half a million tonnes of CO2. The immense amount of material required causes the building industry to be one of the largest emitters of CO2 and responsible for around 40% of energy consumption.

Carbon is a fundamental element of life on earth, and can be extracted from plants, rocks, and even air. Crude oil is currently used to produce carbon, as it is relatively inexpensive and, compared to the required amount, its availability is practically unlimited. However, current research is looking at the possibility of producing carbon from lignins, a product of wood residues left over when manufacturing paper. This method could be put into industrial use within 5 years.

Switching to carbon concrete for the construction and retrofitting of buildings reduces energy consumption and CO2 emissions by 50% and saves valuable resources. Using carbon concrete means we can build with thinner walls, which requires less cement, sand, gravel and water, and furthermore reduces transport costs.

Attractive: Carbon concrete creates an entirely new design language
A durable and resource-efficient composite material, carbon concrete combines strength with flexibility and multi-functionality, making construction maintenance and future construction economical, ecologically sustainable and attractive. "Lightweight building" and "concrete" is no longer a contradiction. The relatively small thickness of the building components allows for a finer and more appealing building style. Thus, it is possible to gain more interior space whilst maintaining the size of the exterior. The flexible but extremely highstrength carbon fabric is easy to process and, due to its enhanced durability, is a suitable as reinforcing material.

Carbon concrete causes a paradigm shift in architecture as well as construction, and is about to create an entirely new design language. In future carbon concrete technology is likely to meet changing user requirements and to adjust to new multifunctional features. Furthermore, carbon concrete creates new opportunities for building retrofitting and strengthening. The innovative building material allows for extremely thin but highly efficient strengthening layers in concrete constructions and is particularly suited to complex boundary conditions and the preservation of historical buildings.

TU Dresden / Institute for Concrete Construction & Institute for Textile Machinery and High Performance Material Technology
With 36,000 students, the Technische Universität Dresden is one of the leading universities in Germany and Europe; strong in the field of research, first-class in diversity and the quality of educational programmes, and closely linked to culture, commerce and society.

Concrete construction has been taught as part of the TU Dresden programme for more than 100 years. The institute includes two professorships. The academic focus in teaching and research lies on all aspects of reinforced concrete in experiments and simulations. Several commercial and industrial partners add to the programme and work together to transfer the results of research to real construction projects.

The research activity of the Institute for Textile Machinery and High Performance Material Technology includes the processing of fibre-based high tech materials with various processing technologies, as well as the functionally integrated development of semi-finished textiles and textile products. In addition, the research activity includes the modelling and simulation of structures and processes at every stage of the textile chain.

The interdisciplinary project “C³ - Carbon Concrete Composite” is one of ten projects funded by the Federal Ministry of Education and Research programme "Twenty20 - Partnership for Innovation" as part of the initiative "Entrepreneurial Regions". The project is managed by the Technische Universität Dresden. The C³ project is working with over 140 partners from research in addition to various companies and associations to develop a new composite material made of carbon fibres and high performance concrete. Thanks to its flexibility and durability, carbon concrete is a resource-efficient alternative to steel reinforced concrete and saves material as well as creating many new design opportunities, characterised by lightness and malleability.

The right to nominate outstanding achievements for the Deutscher Zukunftspreis is incumbent on leading German institutions in science and industry as well as foundations.

The project "Carbon concrete, a fascinating material - economical, efficient, attractive” was nominated by the Leopoldina - the German National Academy of Sciences.
