The flexural strengthening of reinforced concrete structures with carbon reinforced concrete has already been extensively investigated in the past and successfully applied in practice several times. Since 2014, there has also been a German general building approval (Z-31.10-182) for the strengthening of reinforced concrete with textile reinforced concrete. However, the carbon reinforcements have developed further in recent years, which is why the transferability of the known findings to two current carbon fabrics with different impregnations was investigated within the scope of the project "C-3- Carbon Concrete Composite". For this purpose, an extensive test program with a total of 18 large component tests was carried out at TU Dresden. The results obtained are presented and discussed in this article.
