UHPC Steel Fibre is specially designed high-strength steel fiber used in Ultra-High Performance Concrete (UHPC). These fibers provide exceptional tensile strength, ductility, and crack control in very dense, high-strength concrete mixes.

Ultra-High Performance Concrete (UHPC) is an advanced concrete with:

• Compressive strength: 120–180+ MPa

• Very low permeability

• High durability

• Superior tensile performance (with fibers)

Steel fibers are essential in UHPC because they provide tensile capacity and ductility.

UHPC fibers are:

• Very fine diameter

• Short length

• Ultra-high tensile strength

• Precisely manufactured for uniform dispersion

They are usually straight or micro hooked, depending on design requirements.

• Tensile Strength: 2000–3000 MPa

• Dosage: 100–250 kg per m³ (much higher than normal concrete)

⚠ UHPC uses significantly higher fiber content compared to conventional concrete.

Since UHPC contains:

• No traditional coarse aggregate

• Very dense matrix

Steel fibers:

✔ Provide tensile strength
✔ Bridge micro and macro cracks
✔ Improve flexural strength
✔ Increase impact resistance
✔ Add ductility (prevents brittle failure)

Without fibers, UHPC behaves in a brittle manner.
