Non-corrosive carbon fiber-reinforced plastic (CFRP) reinforcements en-able significant reduction in the concrete cover dimensions of concrete components. The high tensile strength of CFRP furthermore allows thin-ner structures. This results in savings of primary resources, thus leading to more CO2-efficient structures. Therewithal, the use of eco-concretes can further enhance this saving effect: Due to their cement-reduced mix-ture compositions, they exhibit a more favorable CO2 balance compared to standard concretes. Therefore, construction elements made of a novel CFRP-reinforced eco-concrete (CFRP EC) combination introduce an in-novative two-track approach for diminishing CO2 emissions. On this ba-sis, the research project "Congreen.Carbon.System” is developing precast frame components made of CFRP-EC for railway construction. In this paper, an eco-concrete and CFRP reinforcement to be used for this pur-pose are presented. Results on the eco-concrete’s strength development as well as on CFRP rebar pull-out tests are presented. Thus, an initial analysis of the bond behavior of eco-concrete with CFRP rebars is per-formed.
