Ultra High Performance Fiber Reinforced
Concrete for structural applications
Keywords
Ultra high performance concrete, fibres, strain
hardening in tension, tensile members, ordinary
reinforcement, ultimate limit state.
Objectives of the Research

• Acquire a better knowledge on the interaction
  between UHPFCR and ordinary reinforcement in the
  tensile zones of structural elements.
• Model the structural response of different type
  of reinforced UHPFRC elements.
• Define suitable applications for UHPFRC with and
  without ordinary reinforcement.

UHPFRC
 Reactive powder matrix  High compressive
strength and High compactness
2 in volume of short steel fibres for ductility
With a strain hardening behavior in pure tension
Test series and results

• New test set up for reinforced members in
  tension
• - 1.6 m long 160 x 160 mm specimens
• - High force potential 180 tons

• Crack pattern development and strain
  localization mechanism followed up to failure

• Influence of the type and amount of steel
  reinforcement on the structural behavior

1.00 m

• Hot-rolled / Cold-worked steel
• Behavior at peak load
• Strain at failure
