Alkali Resistant (AR) Glass Fibers are designed specifically for use in concrete/cement. They are manufactured from a specially formulated glass composition to be suitable for use in concrete. SFT-AR GlassFiber are particularly suitable for Premix GFRC and other mortar and concrete reinforcement applications, such as the general ready-mix concrete and precast industries. They have high tensile strength and modulus, do not rust like steel, and are easily incorporated into concrete mixes. These Alkali Resistant SFT-AR GlassFiber will drastically improve the structural integrity of GFRC mix, general ready-mix and precast concrete, saving weight and money.
