Micro Synthetic Fiber for Concrete Reinforcement
Superior Concrete Fibers for Fiber Reinforced Concrete
PIONEER® Micro Synthetic Fiber
Micro Synthetic Fibers are high-performance polypropylene (PP) and polyester (PET) fibers designed to reduce plastic shrinkage cracking, enhance durability, and improve early-age performance in concrete and mortar.
They serve as secondary reinforcement, distributing stresses more evenly and minimizing crack formation during the critical curing phase.
PIONEER® offers a full range of micro fibers, including monofilament, fibrillated, ultra-fine, self-dispersing, hybrid, and polyester types—engineered for professional concrete performance.

PIONEER® Micro Synthetic Fiber Solutions
PIONEER® offers six types of micro fibers designed for different performance and application requirements.
What Are Micro Synthetic Fibers?
Micro synthetic fibers are thin (10–300 μm), short (6–19 mm) polymer fibers mixed into concrete to provide multidirectional reinforcement.
Unlike steel mesh or macro fibers, micro fibers primarily target early-age plastic shrinkage cracks, improve cohesiveness, and enhance resistance to impact and abrasion.
Key Functions：
-
Reduce plastic shrinkage cracks
-
Improve cohesion and reduce bleeding
-
Enhance early-age tensile strength
-
Increase durability and surface toughness
-
Improve concrete homogeneity and finish quality
Standards & Compliance：
-
ASTM C1116 – Type III Synthetic Fibers
-
EN 14889-2 – Class I Micro Fibers

Industrial and Structural Uses
Slabs-on-grade
Pavements, sidewalks & driveways
Parking decks
Precast & Manufacturing
Precast panels and concrete elements
Pipes, blocks,
Rooftop materials
Mortar, Plaster & Repair
Renders, overlays, screeds
Crack repair mortars
Decorative and architectural concrete
Tunnel & Shotcrete
Shotcrete & tunnel linings
Underground works requiring cohesion improvement
Need Better Crack Control Than Polypropylene Fiber?
Polypropylene fiber is widely used for basic crack control in concrete, especially for plastic shrinkage. It is a practical and cost-effective solution in most standard applications.
However, for projects requiring reduced visible cracking, higher durability, and long-term performance, its effect after hardening can be limited.
Upgrade to Rimix™ NanoRebar
Rimix™ NanoRebar is an advanced micro fiber designed for more efficient crack control.
Its ultra-fine diameter creates significantly more fibers per m³, increasing the chance of stopping micro-cracks early.
With higher strength and modulus, it works in both the plastic and hardened stages, helping improve crack resistance, toughness, and overall concrete reliability — not just early shrinkage control.

Higher Efficiency, Same Cost Level
At roughly half the dosage, NanoRebar delivers more reinforcement points and stronger performance, while maintaining a comparable cost per cubic meter.
It’s a simple upgrade from polypropylene fiber — achieving better crack control without increasing total project cost.

FAQ
Micro synthetic fibers are primarily used to control plastic shrinkage cracking, reduce settlement cracking, and enhance early-age durability in concrete. They help improve surface quality, reduce permeability, and provide better resistance to impact and abrasion.
Micro synthetic fibers are very fine (typically 6–40 μm) and designed for early-age crack control, while macro fibers are longer and thicker, intended to provide structural post-crack reinforcement, often replacing steel mesh or steel fibers.
High-quality monofilament fibers (such as HPM® PP microfibers) do not cause surface fuzzing when correct dosage and finishing methods are used. Fibrillated fibers may slightly increase surface texture but typically disappear during troweling or finishing.
Yes. They can be used in ready-mix concrete, precast, shotcrete, mortar, overlays, repair materials, ultra-thin toppings, and even decorative concrete.
-
Monofilament fibers → Best for finishing quality and plastic shrinkage control
-
Fibrillated fibers → Better bonding and early-age toughness
-
Blended types → Balance of performance and cost
