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.

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：

  1. Reduce plastic shrinkage cracks

  2. Improve cohesion and reduce bleeding

  3. Enhance early-age tensile strength

  4. Increase durability and surface toughness

  5. Improve concrete homogeneity and finish quality

Standards & Compliance：

  1. ASTM C1116 – Type III Synthetic Fibers

  2. EN 14889-2 – Class I Micro Fibers

Benefits of Micro Synthetic Fibers in Concrete

Crack Control Performance :

Fibers chemically inert and uniformly distributed, controlling:

  • Plastic shrinkage cracks

  • Temperature & drying shrinkage

  • Surface microcracks

 Enhanced Durability :

  • Better resistance to impact, abrasion, and chipping

  • Reduced permeability and improved freeze–thaw durability

Improved Workability & Finish :

  • Smoother surface finish

  • Reduced segregation and bleeding

Where to Use Micro Synthetic Fibers

Micro fibers are suitable for nearly all concrete systems, including:
