Abstract:
In this work, the multifunctionality of components made of carbon concrete is examined with regard to possible areas of application and their feasibility. The focus is on the heating of and with carbon concrete components. Within the scope of this investigation, utilisation concepts for functionalised components were first developed. The concepts relevant to heating were then examined with regard to their structural and economic feasibility. In addition, product-specific applications were defined and application potentials in the national and international context were evaluated. The analysis of the utilisation concepts showed that efficient heating is possible via the carbon fibre reinforcement used in carbon concrete. For this, the carbon rods and scrims, which replace the conventional steel reinforcement, must be connected to each other and then connected to a voltage source. Due to the specific resistance of the individual carbon fibre bundles, heat is generated which is transferred to the concrete. The radiant heat generated affects both objects and people. Carbon concrete components can thus replace entire heating systems in buildings, provide a substitute or support winter services by keeping concrete structures free of snow and ice. Due to climatic conditions, the use of heatable carbon concrete components does not make sense in every region of the world. In addition, the lack of an abZ and other regulations make the production process costly and time-consuming. In conclusion, it can be said that there is enormous potential in the use of multifunctional components made of carbon concrete and that it will be necessary to conduct even more intensive research and develop cost-effective manufacturing processes in the future.
