Abstract:
Carbon reinforced concrete (CRC) is a material composed of a high-performance concrete and a carbon
reinforcement (textile grids, lamellas, rods). Composite materials with reinforcements of other fiber materials are
called textile reinforced concrete (TRC). The investigations of CRC started more than 20 years ago and the
continuous development as well as research findings have opened many fields of application. Today, the use of
CRC includes the strengthening of reinforced concrete elements as well as the realization of new elements such as
facades, shells and even bridges.
Some of these structures require knowledge of the fatigue behavior due to cyclic loading (e. g. bridges). In a
collaborative project of the Institute of Structural Concrete of the RWTH Aachen University and the Institute of
Concrete Structures of the TU Dresden, the uniaxial tensile fatigue behavior of two carbon textile reinforcement
types was systematically investigated. The specimens were subjected up to 107 loading cycles and stress ranges
up to 261 ksi (1,800 MPa). The influence of the maximum load and amplitude were investigated as well as fatigue
curves for these two reinforcement types derived.
