DÚCTIL fiber reinforcement enhances the performance of concrete;

• Changing brittleness to ductility
• Providing strength not only under compression but also under flexure
• Enhancing structural and constructional benefits

The improvement in performance of the concrete is dependent upon the physical characteristics and geometry of the steel fiber:

• High modulus of elasticity (200,000 MPa)
• High tensile strength (1100 – 2000 MPa)
• High strength at very low strain
• Negligible relaxation
• Strong anchorage mechanism (end hook shape)
• Fiber length and diameter (so-called “aspect ratio”)
• Appropriate dosage rate (kg/m3) – unit content of steel fibers in concrete
