abstract

which has amorphous structure and its tensilestrength, adhesion performance are outstanding and has wafer type shape comparing to hook type steel fiber. In this study, in regard to specimen with wafer type shape steel fiber and amorphous steel fiber, flexural behaviors were evaluated in shape of fiber and adhesion performance. As a result, wafer type shape steel fiber reinforced concrete showed fracture behavior as fiber pulled out from concrete. On the other hand, adhesion performance of amorphous steel fiber reinforced concrete was high but it showed brittle fractural fracture behavior by shear fracture result from wafer type shape.
