Understanding what is GFRC

GFRC (Glass Fiber Reinforced Concrete) or “lightweight concrete” in layman’s terms, also known as GRC (Glass Reinforced Concrete) or FRC (Fiberglass Reinforced Concrete) is an amalgamation of materials that are used in countless architectural and civil engineering design products. For the past 30 years, GFRC has been used to create coping, column wraps, cladding panels, wall cap, pier caps, pavers, balustrade systems, monument signs, fireplace, columns, window surrounds, benches, panels, statues, barricades, domes, planters, ornaments, countertops, artificial rock/stone work and a multitude of other applications that are limited only to the architect and his imagination.

GFRC is a cement-based composite material reinforced with alkali-resistant fibers. Although the properties of Glass fiber Reinforced Concrete (GFRC) vary according to the production method, mix design, and the type and content of the alkali resistant Glass fiber, the generic composition of GFRC is a mixture of cement (usually Portland cement), water, fine aggregate, chemical admixtures, and alkali resistant glass fibers (AR glass fibers) randomly dispersed throughout the sand/cement matrix. For further information refer to PCI MNL 128 Appendix J. For specifications go to the APA website at www.archprecast.org/gfrc.htm.

The benefits and use of GFRC are as follows:
  • Higher flexural, tensile, and impact strength than normal concrete
  • Low shrinkage rates
  • Proven engineered composite material
  • Great for historical reconstruction for replacing original cement/concrete designs.
  • Can be made to look like traditional precast, terra cotta, carved stone, cast stone, or limestone building components
  • Strong and durable (against fire, water, freezing temperatures, and salt)
  • Wonderful for concrete wall panel construction
  • Unlimited design and aesthetic selections
  • Natural look in a custom design without using real stone
  • Lower installation costs
  • Faster installation
  • Lightweight (up to 12 times less weight than regular cement or concrete)
  • No rust or corrosion
