Abstract
In this study, in order to obtain mechanical properties of hardened carbon fiber reinforced concrete (CFRC), compression, bending, fracture toughness and flexural fatigue testings were conducted. From the results, following items were investigated and discussed: 1) fundamental mechanical properties such as Young's modulus and compressive and flexural strengths, 2) tension-softening curves and J-integral values estimated by means of an inverse analytical approach using the cohesive force model, 3) evaluation of size effects on flexural strength based on a highly-stressed volume concept, and 4) flexural fatigue endurance and residual flexural strength after fatigue testing.
