the Effect of Steel Fiber on the Tensile Strength of the High Performance Steel Fiber Reinforced Cementitious Composites

초세립 미립자로 구성된 고성능 SFRC에서 강섬유의 혼입에 따른 인장강도의 변화

High performance SFRC composed of mira-sized ultra fine particles is characterized by high strength, high ductility and excellent durability. therefore many researches about materials based on new composition like this are performed recently. many researchers have reported that adding steel fiber to concrete improved its tensile and flexural strength significantly. the main objective of this research is to examine the effect of adding steel fiber on the tensile strength of high performance SFRC. variables considered in this study are w/c ratio and fiber volume fraction.
