AR Glass Fibers are designed specifically for use in concrete. Alkali Resistant (AR) Glass fibers are manufactured from a specially formulated glass composition with an optimum level of Zirconia (ZrO2) to be suitable for use in concrete. These AR fibers are designed to resist breaking down during mixing and processing so that it stays basically as a bundle of filaments. These products are particularly suitable for Premix GFRC and other mortar and concrete reinforcement applications. AR glass fiber have high tensile strength and modulus, do not rust like steel, and are easily incorporated into concrete mixes.
Our fibers are 19mm (3/4”) in length with, 200 filaments per stand, with a filament diameter of 18 microns. These fibers impart strength in a concrete unit due to their bundled nature. Due to the fact that they are bundled fibers, they are more likely to show up in finished surfaces if precautions are not taken. See recipes section to read more about this.
