About this item

  • Diameter is 17 microns.
  • Regular concrete mix dosage: We recommend 6-8 pounds of basalt chopped fibers per cubic yard of concrete.
  • GFRC concrete mix Fiber content varies but is generally approximately 3% to 7% of the cementitious material weight or 1% to 3% by total concrete weight. Increased fiber content adds strength but decreases workability. Common water to cement ratios used from 0.25 to 0.35. (25-35% by cementitious material weight)


Basalt Chopped Fibers can be mixed directly into polymers and concrete to increase tensile strength, reduce cracking and chipping. Perfect for mortar and concrete reinforcement applications; all decorative applications as countertops, fireplace surrounds. Basalt Fiber has a similar chemical composition as regular glass fiber but Basalt Fiber has better strength characteristics, and unlike most glass fibers is highly resistant to acidic and salt attack and alkaline, making it a good option for concrete, bridge and shoreline structures.
