Since 2002, we have specialized in concrete crack resistance, waterproofing, and anti-corrosion technologies.
Blended Twist Macro Synthetic Fiber for Concrete
Reliable Toughness, Crack Control & Post-Crack Performance for Fiber-Reinforced Concrete
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.

Looking for Better Macro Synthetic Fiber Performance?
Standard PP macro synthetic fiber is widely used in fiber reinforced concrete, but its performance is often limited by material properties and manufacturing methods.
With lower tensile strength and a relatively smooth surface, conventional macro fibers provide limited anchorage and weak crack-bridging ability after cracking.
In real projects, this often results in insufficient post-crack strength, uneven performance, difficult finishing, and higher dosage just to meet basic requirements.
How Rimix™ 3D Improves Macro Fiber Performance
Rimix™ 3D is a high-performance upgrade to conventional macro fiber, engineered with advanced PP–PE composite materials.
It delivers higher tensile strength and modulus, allowing better load transfer across cracks and more stable post-crack performance.
Its optimized fiber geometry enhances bonding and pull-out resistance, while ensuring excellent dispersion without balling—making mixing and finishing easier on site.
Compared to standard macro fiber, Rimix™ 3D achieves stronger reinforcement with lower dosage, improving both performance and cost efficiency.

Upgrade Fiber Performance — Not Just Dosage
Simply adding more fiber does not always solve performance issues. The key is upgrading the material quality and structural performance of the fiber itself.
Rimix™ 3D provides higher efficiency per kilogram, helping achieve better crack control, improved workability, and more consistent concrete performance across different applications.

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.
