12mm AR Glass Fiber ≥ 16.7% ZrO2 – 1kg Pulpable Toss-In Bags
12mm AR Glass Fiber ≥ 16.7% ZrO2 – 1kg Pulpable Toss-In Bags
12mm Alkali-Resistant Glass Fiber – ≥16.7% ZrO2 Content
Engineered for long-term durability in cementitious environments, our 12mm AR (Alkali-Resistant) glass fiber delivers superior resistance to the high-pH conditions found in concrete and mortar. With a minimum ZrO2 (zirconia) content of 16.7%, this fiber maintains its integrity and reinforcing performance over the life of the structure. Pre-packaged in 1kg pulpable toss-in bags for clean, accurate, and effortless dosing on the job site.

Frequently Asked Questions
Why is ZrO2 content important?
Zirconia (ZrO2) is what makes glass fiber alkali-resistant. Standard glass fiber degrades rapidly in the high-pH environment of concrete. A minimum of 16.7% ZrO2 ensures the fiber retains its strength and reinforcing properties over the long term.
Does the bag need to be opened?
No. The pulpable bag dissolves completely in the mixer — simply toss the 1kg bag in whole. No tearing or measuring required.
What is the recommended dosage?
Dosage depends on the application and mix design. Contact us for project-specific guidance.
Is AR glass fiber compatible with admixtures?
Yes. AR glass fiber is compatible with standard concrete and mortar admixtures.
