섬유 혼입 비율에 따른 섬유보강 콘크리트의 재료특성

Material property of fiber reinforced concrete according to the fiber blended ratio

In this paper, material property of fiber reinforced concrete(FRC) according to the steel fiber, glass fiber and carbon fiber blended ratio. The fiber reinforced concretes are increased mechanical strength, because the fibers are dispersed with randomly direction and disturb crack progression in concretes. Adhesive fracture is occurred slowly at interface between fiber and concrete, and the fracture energy is absorbed due to softening phenomenon.
