Applications of carbon fiber reinforced concrete (CFRC) to various building materials have been progressed because of its excellent mechanical characteristics. The conventional CFRC made of mortar with no coarse aggregate has some defects such as large drying shrinkage and low modulus of elasticity, which will be reduced by substituting concrete-mix including coarse aggregate for the mortar. In this study, in order to develop the CFRC using concrete-mix, experimental investigations were conducted concerning evaluations of an optimum mix proportion and various mechanical characteristics of the CFRC. As the results, it was shown that the CFRC of concrete-mix was superior in modulus of elasticity, flexural and fracture toughnesses to that of the mortar-mix and the mechanical characteristics of the former was, if anything, similar to those of steel fiber reinforced concrete.
