Amorphous metallic fiber has higher tensile strength as well as corrosion and wear resistance than common, crystalline steel fibers. Its utilization as reinforcement improves the crack resistance and flexural and tensile performance of concrete. In the study at hand, the tensile behavior of thin plate amorphous metallic fiber-reinforced cementitious composites (AFRCC) is compared with that of hooked steel fiber-reinforced cementitious composites (HSFRCC) for both quasi-static and dynamic loading regimes. AFRCC exhibites a high stress distribution effect and higher tensile strength, strain capacity, and peak toughness than HSFRCC, but lower tensile toughness and lower dynamic increase factor values for tensile strength, strain capacity, and toughness.
