Understanding the thermal behavior of carbon textile reinforced concrete is essential to ensure reliable mechanical performance, as temperature exposure can significantly influence strength, stiffness, and durability, and must therefore be considered during structural design. In addition to the characterization under ambient conditions, this thesis also characterizes the application of electrically heated carbon textile reinforced concrete to enable functional building components. The combined analysis highlights the potential of carbon textile reinforced concrete for integrated thermal performance in construction. The thermal response of carbon textile reinforced concrete was examined across a wide ambient temperature range, including freeze-thaw exposure, service temperatures up to 80 °C, and elevated thermal conditions up to 1000 °C. To support mechanical characterization, tensile strength tests were conducted on the carbon textile reinforcement, the cementitious matrix and the composite. Using a comparative approach based on KT-values, which relate tensile strength at elevated temperatures to that at room temperature, it was shown that thermal loading leads to a gradual decrease in tensile strength. This is primarily caused by softening and degradation of the impregnation material, and at higher temperatures, by carbon fiber decomposition. Digital image correlation measurement was implemented to analyze deformation and cracking behavior under thermal load. A methodological contribution of this thesis is the development of an automated evaluation tool for digital image correlation measurements, enabling standardized, reproducible, and efficient analysis across test series. In addition to characterizing mechanical performance under ambient temperature, the electrical thermal behavior was investigated to understand the underlying heating principles. Within the carbon textile reinforced concrete composite, multiple technical heating principles, such as electrical resistance, contact, convection and radiant heating were identified. Experimental investigations revealed that key factors influencing the mechanical and electrical behavior include the geometry of the carbon textile reinforcement, the fiber content, and particularly the type of impregnation. The integration of carbon textile reinforced concrete as a functional heating element was further supported by numerical modeling of heat development under electrical loading, providing design- oriented insights for practical application. The findings provide a basis for the development of advanced multifunctional systems, including automated de-icing elements and thermally controlled concrete surfaces. %F PUB:(DE-HGF)11 %9 Dissertation / PhD Thesis %R 10.18154/RWTH-2025-10011 %U https://publications.rwth-aachen.de/record/1022421
