High-performance AR Fiberglass Reinforcement | PIONEER®
Alkali-Resistant Glass Fiber Reinforcement for Concrete and GFRC
What Are PIONEER® Alkali-Resistant Glass Fibers for Concrete?
PIONEER® HPM® AR is a zirconia-rich, alkali-resistant chopped fiberglass fiber designed to improve crack control and durability in concrete, GFRC, and UHPC applications. These AR glass fibers disperse easily without clumping, forming a high-performance reinforcement network that reduces plastic shrinkage and drying shrinkage cracking while enhancing flexural and tensile strength in both plastic and hardened concrete stages.

How Alkali-Resistant Glass Fibers Strengthen Concrete？
AR fiberglass fibers enhance crack resistance and toughness while maintaining workability.
PIONEER® HPM® AR glass fibers form a three-dimensional reinforcement network within concrete and mortar, effectively reducing plastic shrinkage, controlling microcracks, and increasing tensile and flexural strength. Ideal for GFRC, UHPC, precast elements, tunnel linings, and marine structures, these fibers ensure durable, crack-resistant concrete even in harsh environments.

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
Alkali Resistant glass fiber is a specially formulated glass fiber containing zirconia (ZrO₂), designed to withstand the highly alkaline environment of cement-based materials. It is commonly used in concrete, mortar, and GRC/GFRC applications to improve crack control and durability.
Standard glass fiber degrades rapidly when exposed to the alkaline conditions found in cement and concrete. AR glass fiber, with its high zirconia content, offers significantly improved resistance to alkali attack, making it suitable for long-term use in cementitious systems.
AR glass fiber is widely used in:
-
GRC / GFRC components
-
Mortars and render systems
-
Precast concrete elements
-
Architectural façade panels
-
Thin-section concrete products
-
