Comparative Bond Characteristics of Amorphous Steel Fiber and Conventional Steel Fiber in Cement Mortar

시멘트 모르타르 내 비정질 강섬유와 일반 강섬유의 부착특성 비교

It is well known that the bond characteristics of fiber govern the performance of fiber reinforced composite material. A preliminary study was carried out to investigate the pull-out behavior of amorphous and conventional single fiber in cement mortar in accordance with the JCI(Japan Concrete Institute) SF-8. The test was performed under displacement control, and results showed that the bond strength decreased with increasing fiber length. In addition, the amorphous steel fiber showed much higher pull-out load per unit weight compared to conventional steel fiber.
