HTM® Twist Blend Macro-Micro Synthetic Fiber
Combined Fiber Reinforcement for Early-Age and Post-Crack Performance
What Is HTM® Twist Blend Macro-Micro Synthetic Fiber ?
HTM® Twist Blend combines twisted macro synthetic fibers with micro polypropylene fibers in a single blended reinforcement system. The macro component is designed to support crack bridging, toughness, and post-crack performance, while the micro component increases fiber distribution during the early stages of concrete hardening. The blend is intended for applications where both early-age crack-control objectives and hardened-concrete performance are considered in the same fiber system.

How the HTM® Macro-Micro Blend Works
HTM® Twist Blend combines two different fiber scales. The micro component is distributed at high fiber count within the fresh concrete and is intended to support early-age crack-control functions. The twisted macro component becomes more important after cracking, where fiber bridging and pull-out behavior contribute to toughness and residual performance.

Key Benefits of HTM® Twist Blend
-
Macro + Micro Fiber System
Combines two fiber scales in one product to address different stages of concrete performance. -
Early-Age Fiber Distribution
Micro polypropylene fibers provide a high number of fine fibers throughout the fresh concrete matrix. -
Post-Crack Reinforcement
Twisted macro fibers are designed to bridge cracks and contribute to toughness and residual performance after cracking. -
Three-Dimensional Reinforcement
Both fiber components disperse throughout the concrete to provide multidirectional reinforcement. -
Non-Corrosive Fiber System
Polymer fibers do not rust, making the system suitable for projects where corrosion-related durability is a concern. -
Simplified Dosing
A pre-blended fiber system can simplify the use of macro and micro fibers where both are required by the selected solution.

Usage Guidelines for Macro Synthetic Fiber Reinforcement
Optimize your concrete performance with PIONEER® HTM® Twist Blend macro synthetic fibers.
-
Dosage: 1.8–4.5 kg/m³, typically 3 kg/m³
-
Mixing: Add with aggregates during batching; extend mixing for uniform dispersion
-
Placement: Compatible with standard placement and finishing practices
-
Note: Replaces secondary mesh; does not replace primary structural rebar if required
HTM® Twist Blend dosage should be selected as a complete blended product rather than by independently calculating the macro and micro components. Recommended dosage depends on the application, concrete mix, required early-age performance, post-crack performance, and project design.

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.
