Alkali Resistant (AR) Fiberglass Roving 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.
Contains minimum of 17% Zirconia
Increase Tensile Strength (three times higher than steel)
High young's modulus
Excellent choppability and dispersion
Outstanding mechanical properties
Suitable for high-speed spray-up process with robots
