GFRC Resources

There's a ton of information available on GFRC and also some training and free technical advice:

  • Nippon Electric Glass America will provide training and technical support. NEG America's Michael Driver recommends that manufacturers interested in producing GFRC products need to participate in hands-on training prior to any attempts at making this type of material. "Most GFRC mixes contain more cement than aggregate and typically include acrylic latex polymers for curing," he said. "Variables such as cement chemistry, aggregate gradation and shape, mix temperature, water chemistry, water reducing admixture type, AR glass fiber aspect ratio, fiber orientation, fiber content, and curing conditions are just a few that need to be considered. Without knowledge of these variables, the novice GFRC manufacturer can become discouraged after just a few failed attempts."
  • The Precast/Prestressed Concrete Institute has a wealth of information on GFRC manufacturing in PCI MNL-128 Recommended Practice for Glass Fiber Reinforced Concrete and PCI MNL-130 Quality Control Manual for GFRC.
  • ACI's state of the art report on fiber reinforced concrete, ACI 544.1R-96, is slightly old now (1996) but has a long chapter on GFRC.
  • Stromberg Architectural Products, which manufactures architectural accents, has an extensive handbook on GFRC that is available for free download.
  • The Glassfiber Reinforced Concrete Association, the GRCA, is a British-based but international association dedicated to advancing knowledge on GFRC. They have an excellent brochure on GFRC applications, called "GRC in Action," that is available for free download.
  • Jeff Girard, founder and president of The Concrete Countertop Institute, authored this introductory article about GFRC. Find information about GFRC history and application, structural properties, how the fibers work, GFRC mix designs, casting methods, and more.
