Ultra-High Performance Concrete (UHPC) delivers exceptional compressive strength, durability, and density—but the matrix alone is brittle. Duraflex™ UHPC Micro Steel Fibers transform UHPC into a ductile, high-performance composite by adding the tensile capacity and crack control needed for structural reliability.
These short, high-tensile fibers (2,500–2,850 MPa) with diameters of 0.16–0.3 mm and lengths of 6–14 mm create a multi-directional reinforcement network. Brass/copper coatings enhance bonding and corrosion resistance.
By dispersing throughout the matrix, the fibers provide the ductility, toughness, and crack bridging needed to unlock UHPC’s full strength in real-world structural applications.
Designed to enhance UHPC performance through improved ductility, crack control, and structural efficiency across advanced construction applications.
Increase Strength & Ductility: Enables UHPC to reach 26–30 ksi compressive strength with controlled post-crack behavior.
Superior Crack Control: Arrests micro-cracks at early stages for smoother, more durable surfaces.
Improve Durability: Low porosity and fiber reinforcement extend service life beyond 75 years.
Enhance Shear & Flexural Capacity: Reduces need for stirrups and improves failure mode predictability.
Maintain Workability: Fibers distribute uniformly, preserving UHPC’s self-consolidating flow.
Optimize Material Usage: Enables lighter, thinner elements with significant material savings.
