Alkali Resistant Glass Fiber

Owens Corning Alkali Resistant Glass fibers will improve the structural integrity of your GFRC mixes with the thin 1/2 in fibers (13 mm). Glass fibers in concrete strengthen with improved finishes and greatly reduced weight - as little as 1/8th of the weight of the equivalent concrete product. All OC alkali resistant glass fiber products are manufactured in compliance with ASTM C1666/C 1666M, EN 15422 and under recommendations of PCI and GRCA.

 When 2 to 5% of Owens Corning Glass Fiber are mixed into a simple 1:1 cement :sand and water matrix, a thin but strong form of concrete is produced. - GFRC. GFRC has a high compression strength along with good tensile and bending properties so products can be designed in thin sections 1/2" glass fiber sections.

Silica Systems, Inc. is one of the leading alkali-resistant glass fibre supplies. Ships worldwide from California.

  • Type of Glass: Alkali Resistant, high Zirconia Content.
  • 17% zirconia content (Zirconia makes the glass fiber alkali resistant). The higher the zirconia content the better the resistance to alkali attack.
  • Fiber filament diameter is 18 microns.
  • Moisture Content < 0.5%
  • Filaments per Strand 200. With 200 filaments in each 18 micron strand, fibers have an outstanding resistance to breaking during the mixing process.
  • A smaller fiber diameter has its advantages allowing for more individual fibers in each pound and concrete with three times the tensile strength of steel reinforced concrete. 
  • Alkali Resistant glass fibers are mixed in to Pre-Cast concrete and GFRC mixes to greatly increase its flexible strength.
  • Alkali Resistant Fibers have a higher specific gravity, giving it a big advantage over other types of fibers. AR fiber will have the same gravity as the aggregate, making the fibers stay away from the surface of the concrete.
