6mm Alkali resistant Glass fiber for UHPC AR fiberglass chopped strand for GRC

Alkali Resistant (AR) Glass Fibers are designed specifically for use in concrete. They are manufactured from a specially formulated glass composition with an optimum level of Zirconia (ZrO₂) to be suitable for use in concrete. AR Glass Fibers are particularly suitable for Premix GFRC and other mortar and concrete reinforcement applications. They have high tensile strength and modulus, do not rust like steel, and are easily incorporated into concrete mixes.

Our fibers are 6mm -9mm-12mm in length, with 200 filaments per strand bundle and a filament diameter of 18 microns. While the bundles are designed to resist breaking down during mixing, care must be given not to overmix. Compared to monofilament fibers (PVA, AC50), bundled fibers are more likely to be visible in finished surfaces if precautions are not taken.

Typical load range: 3% by weight of the total mix,9kg per bag ,486-756kg/pallet.

All of our alkali resistant glass fiber products are manufactured in compliance with ASTM C1666/C 1666M, EN 15422 and under recommendations of PCI and GRCA.

• The primary benefit of AR Glass Fiber is the strength they provide relative to how they effect the workability of the concrete mix during application. Generally put, glass fibers produce good strength, and are easy to work with.
• Scrim provides a great way to provide localized strength in specific tensile planes. To understand where these tensile planes occur, read THIS ARTICLE.
• AR Glass fiber provides a great strength to cost ratio.
• High Elastic Modulus 10 times that of polypropyleneExcellent
• Corrosion Resistance Alkali and acid resistantEasy to Incorporate
• Do not protrude or spring back from the surface
• Disperse instantly in the concreteSafe to Use Inorganic, incombustible, with no health risk

Dosage-

Dosages rates of glass fibers vary heavily depending on the application and desired outcome. Dosage can range from 1% to 6%. This depends heavily on the mix recipe, mixing process, and application method. In most artisan mixes, a dosage rate around 3% is most appropriate.
