ECOCRETE™ Milling Steel Fiber

Wave-profiled, crescent-section steel fibers for crack control, toughness and long-life floors.

What is Milling Steel Fiber?

Milling Steel Fiber is produced by mechanically milling thick steel plates or steel ingots into short fibers. Compared with drawn wire fibers, milling fibers feature a wavy exterior and crescent-shaped section that grip the matrix, promoting bond and post-crack energy absorption. The fibers disperse well, do not ball, and help reduce crack width and density while simplifying construction versus secondary mesh.

ECOCRETE™ Milling Steel Fiber is milled from thick steel plate/ingot. Its unique wavy surface and crescent cross-section deliver strong mechanical interlock with cement paste, improving crack control, flexural capacity, impact resistance and fatigue durability in industrial floors, pavements, pipes, bridges and hydraulic works.

Key Benefits of Milling Steel Fiber

  1. Crack Control & Tightness — Bridges plastic/drying shrinkage and service cracks; reduces crack width for better durability.
  2. Toughness, Impact & Fatigue — Crescent section and wave profile raise pull-out resistance and post-crack energy absorption for heavy-duty slabs and pavements.
  3. Uniform Dispersion — Designed to mix evenly without balling; pump- and screed-friendly for large pours.
  4. Construction Efficiency — Can reduce or replace secondary mesh in many crack-control specifications; compatible with laser screeding; helps shorten schedules and save cost.
  5. Clean Bonding Surface — Rough, clean steel surface forms a strong grip with cement paste.

Applications of Milling Steel Fiber

  1. Building & Precast: housing slabs, precast piles, frame nodes, roof/underground waterproof layers.
  2. Industrial Floors: cut-joint, jointless and seamless floors; pile-supported floors; garage leveling layers; composite deck slabs; rafts; plant roads and pavements.
  3. Pipes: centrifugal, vibration and extruded pipes; pump pipes; steel-lined steel-fiber pressure pipes.
  4. Highways & Bridges: box arches, continuous box girders, bridge decks/overlays; cold-region/airport pavements.
  5. Rail: prestressed sleepers (mono-block/twin-block).
  6. Water & Hydropower: abrasion/erosion zones, gates/sluices, spillways, dam face slabs.
  7. Ports & Marine: steel pipe-pile anticorrosion layers, quay/jetty works, subsea concrete.
  8. Other: heavy-duty factory/warehouse floors, silos, repair & strengthening, manhole covers, trench grates, underground cable/pipe works.

How to Use & Recommended Dosage

  • General slabs / industrial floors: 20–40 kg/m³ (optimize by joint spacing, wheel loads and curling control).
  • Heavy-duty pavements / bridge decks / precast: 30–60 kg/m³ depending on residual-strength targets.
  • Shotcrete / repairs: 25–45 kg/m³ (verify pumpability with a trial panel).
  • Design note: Milling Steel Fiber enhances crack control and toughness but does not replace primary reinforcement where required. Follow the structural engineer’s design and local codes.

Mixing sequence (cementitious): Aggregates → Milling Steel Fiber (dose gradually) → cement → water + admixtures → mix to full dispersion; use superplasticizer to maintain slump/flow.
Tips: For thin toppings select 32–35 mm; for industrial floors/bridge decks use 45–50 mm.

FAQs — Milling Steel Fiber

A: Milling fibers have a wavy surface and crescent cross-section for strong mechanical interlock; they disperse well and offer robust crack control and toughness at practical dosages.

A: In many crack-control specs it can reduce or replace secondary mesh—subject to structural design. Primary load-bearing reinforcement must follow code.

A: Expect some slump reduction. Use gradual dosing and superplasticizer to maintain workability; finishing remains compatible with screeds/laser screeds.

A: 32–35 mm for thin toppings/repairs; 45–50 mm for industrial floors and bridge decks requiring higher residual strength.

A: COA / SDS / TDS with each batch; ISO 9001 system; project inspection files on request.
