Twisted Macro Synthetic Fiber for Fiber-Reinforced Concrete | PIONEER®

Advanced crack control with non-corrosive macro fiber reinforcement

Upgrade your concrete with PIONEER® HTM® Twist, a twisted monofilament macro synthetic fiber engineered to deliver superior crack control, residual toughness and long-term durability for slabs, shotcrete, precast and industrial flooring. Request a tailored dosage or a quote today.

What Are PIONEER® HTM® Twist Macro Synthetic Fibers?

PIONEER® HTM® Twist is a premium macro synthetic fiber made from 100% virgin polypropylene with a unique twisted monofilament bundle design. When mixed into concrete or shotcrete, HTM® Twist creates a 3-D polymer network that improves bonding, increases post-crack residual strength and controls plastic and drying shrinkage cracking — all without the corrosion risk associated with steel fibers.

Key quick facts

  • Replaces steel fibers and welded wire mesh in many applications.

  • Smooth finish and pumpable for shotcrete mixes.

  • Effective across slab-on-grade, precast, shotcrete and industrial flooring applications.

  • ASTM D7508: Standard Specification for Macro Synthetic Fibers for Concrete

How Twisted Macro Fibers Enhance Fiber-Reinforced Concrete

HTM® Twist fibers form a uniform, three-dimensional reinforcement network inside concrete and shotcrete, bridging micro- and macro-cracks to maintain load transfer after cracking. Their twisted bundle structure enhances mechanical anchoring to the cement matrix, improving impact, fatigue, and bending resistance. It is a preferred alternative to welded wire mesh and steel fibers, particularly effective in projects requiring corrosion protection, ease of installation, and cost optimization.

Key Benefits of Using HTM® Twist Macro Synthetic Fibers

  • Replaces steel fibers and welded wire mesh for many concrete reinforcement uses.

  • Controls plastic and drying shrinkage cracking to protect structural integrity.

  • Improves toughness, impact and fatigue resistance on heavy-duty surfaces.

  • Non-corrosive — ideal for harsh or corrosive environments.

  • Lightweight, easy to dose and compatible with automated batching systems.

  • Enables thinner slabs or overlays while maintaining performance (cost-saving).

  • Lower installation time and labour compared with mesh/steel reinforcement.

Applications of HTM® Twist in Concrete and Shotcrete

PIONEER® HTM® Twist is tailored for demanding FRC (Fiber-Reinforced Concrete) use cases:

  • Industrial floors & heavy-duty slabs-on-ground — improved abrasion & fatigue resistance.

  • Shotcrete (tunnels, slopes, mining, underground) — pumpable and improves post-crack behaviour.

  • Precast elements (tanks, pipes, panels) — reduces cracking risk, simplifies handling.

  • Bridge decks, parking structures, ramps & overlays — durable, corrosion-free reinforcement.

  • HPC/UHPC applications needing distributed polymeric reinforcement.

Usage Guidelines for Macro Fiber Reinforcement in Concrete

Follow these guidelines to achieve consistent dispersion and effective reinforcement with PIONEER® HTM® Twist fibers.

  • Dosage: 1.8–4.5 kg/m³, typically 3 kg/m³ for effective crack control.

  • Mixing: Add fibers during batching or with aggregates; extend mixing to ensure even distribution.

  • Placement: Use standard methods for fiber-reinforced concrete; fibers remain embedded, allowing a smooth finish.

  • Note: Replaces secondary mesh reinforcement but does not replace primary structural rebar if required by codes.
