Maintaining buildings, bridges and towers is time consuming and costly. The reason is the reinforced concrete used in many structures: the steel reinforcing bar can corrode, making the building material crack. Is it possible to replace it with a more robust alternative?

Prof. Manfred Curbach, Prof. Chokri Cherif and Prof. Peter Offermann were significantly involved in the development of one of these alternatives. They elaborated an innovative concrete-composite material that is considerably more durable than steel reinforced concrete and gives architects new design options. Instead of an iron core that is subject to corrosion, this concrete contains carbon: a fabric made of fine carbon fibres. Carbon concrete is durable, environmentally friendly and versatile in its uses. The three nominees conduct research at the Technische Universität Dresden: Manfred Curbach is head of the Institute for Solid Building Construction, Peter Offermann is Professor Emeritus at the Institute for Textile Machines and Textile High Performance Materials Science that is currently chaired by Chokri Cherif.

Reinforced concrete (RC) has been the material most frequently used in residential and industrial buildings, factories, bridges, tunnels, towers and concrete masts since the 1950's. As rebar, ribbed steel rods are placed in concrete to improve stability since it combines the compressive strength of concrete with the tensile strength of steel. Yet it has its disadvantages as well. RC manufacture uses a lot of energy and accounts for a high percentage of the construction industry's CO2 emissions. Reinforced concrete structures are also an increasing safety risk: since steel is threatened by corrosion, structures have a limited life span of around 40 to 80 years. This is one of the reasons why many of the 120,000 bridges in Germany will need maintenance work in the next few years. This goes hand-in-hand with costs totalling billions of Euros. Replacing steel-reinforced concrete with carbon concrete can largely avoid expensive repairs and also lower the use of resources.

The carbon used to reinforce concrete is even stronger than steel, but at the same time much lighter and more durable since it does not corrode. Building elements made of carbon concrete can thus be thinner, reducing demand for raw materials. Energy use and CO2 emissions are cut almost in half. Very intricate structural designs are possible thanks to the flexible ductility of the carbon fibres, increasing the useful life of the structures beyond that of those made of steel reinforced concrete.

Carbon concrete can be used to maintain and save homes, bridges or masts that are at risk structurally. It has already been in use since 2006: by applying a thin layer of carbon concrete, the life span of commercial buildings, bridges, and facade elements can be extended considerably. On new structures, the smaller size and lower weight of the concrete structural elements with carbon are significant. For example, façade panels of carbon concrete are only about two centimetres thick, whereas if made of steel reinforced concrete, they would be eight centimetres thick. This reduces the cost of production, transport and installation. Since much less material is needed, the material costs of carbon are comparable to those of steel in regard to performance. Modules made of carbon concrete can also be made to serve other functions, such as in insulation, heating or for monitoring, adding built-in "intelligent networking" capabilities to buildings or bridges.

Germany heads worldwide research into the principles and applications of the revolutionary building material. An extensive project launched in 2014 is designed to further shore up and expand on this leading role. The project "C3 – Carbon Concrete Composite" with some 140 participating institutes and enterprises is financed with Euro 45m from the Federal Ministry of Education and Research (BMBF) as well as Euro 25m in equity capital. TU Dresden serves as the consortium leader whose chairman is Manfred Curbach. The researchers are paving the way to the market for carbon concrete and laying the foundation for its general use in the construction industry. The potential is enormous: around 160m tonnes of steel are used worldwide every year to reinforce concrete, 4m tonnes in Germany alone. The aim is to use carbon to reduce this amount by 20% over the next ten years.

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.
