Paper Title:
Influence of Fiber Geometry on the Mechanical Properties of Ultra-High Performance Fiber Reinforced Concrete (UHPFRC)
  Abstract

Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) has been a technological breakthrough offering compressive strength over 100MPa and tensile strength over 10MPa with true ductile behavior. Three types of frequently used fibers including flattened end, hooked end and crimped fibers, were used in producing UHPFRC with fiber volume ratios of 1%, 2%, 2.5% and 3% to investigate different reinforcing effect of fiber geometry on UHPFRC. The results showed that specimens with flatted fibers showed the highest flexural tensile strength, and specimens with crimped fibers showed the lowest flexural tensile strength. The optimum volume ratio for the flattened end fibers or hooked end fiber was 2%. The hooked end fibers were more preferable for producing ductile UHPFRC.
