Blended Twist Macro Synthetic Fiber for Concrete | PIONEER®

Reliable Toughness, Crack Control & Post-Crack Performance for Fiber-Reinforced Concrete

Upgrade your fiber-reinforced concrete and shotcrete with PIONEER® HTM® Twist Blend, a high-performance twisted monofilament macro synthetic fiber. It combines HTM® Twist macro fibers with HPM® PP microfibers, delivering stronger mechanical anchorage, improved toughness, and reliable crack control—offering steel-fiber-equivalent performance without corrosion risks.

What Is PIONEER® HTM® Twist Blend Macro Synthetic Fiber?

PIONEER® HTM® Twist Blend is a structural macro synthetic fiber made from 100% virgin polypropylene. Its twisted monofilament profile delivers high mechanical interlock and enhanced bond with the cement matrix, resulting in superior post-crack load capacity, impact resistance, and fatigue performance.

HTM® Twist Blend is designed to replace welded wire mesh and steel fibers in slabs, shotcrete, industrial floors, precast components, and composite metal decks.

The twisted structure improves stress distribution, reduces major cracking, and strengthens concrete across both plastic and hardened stages—while maintaining excellent workability.

FAQ

  • HTM® Twist Blend is a blended macro synthetic fiber combining twisted monofilament polypropylene fibers with HPM® PP microfibers. The twisted profile provides superior mechanical anchorage, improving crack control, toughness, and durability in concrete and shotcrete.

  • The fiber’s twisted geometry creates 3D mechanical interlock with the cement matrix. This increases pull-out resistance, enhances post-crack load capacity, and provides steel-fiber-equivalent toughness without corrosion risks.

  • Typical dosages range from 3.0–6.0 kg/m³ depending on performance requirements:

    • 3.0–4.0 kg/m³ — Crack control, joint reduction

    • 4.0–6.0 kg/m³ — Industrial floors, precast, shotcrete

    • Higher dosages available for heavy-duty or high residual strength needs

  • HTM® Twist Blend is ideal for:

    • Industrial floors & pavements

    • Slabs-on-grade

    • Composite metal decks

    • Tunnel shotcrete & mining

    • Precast pipes, tanks, and walls

    • Bridge decks & overlays

  • Yes. It works with normal concrete, pumped concrete, shotcrete, precast mixes, SCC, and high-performance concrete. Only slight mix adjustments (e.g., superplasticizer tuning) may be needed at higher dosages.
