Glass Fiber Reinforced Concrete(GRC)

GRC also called GFRC is a composite of Portland cement, fine aggregate, water, acrylic co-polymer, (AR) glass fiber reinforcement and additives. The AR (alkali resistant) glass fibers reinforce the concrete, much as steel reinforcing does in conventional concrete. The glass fiber reinforcement results in a product with much higher flexural and tensile strengths than normal concrete, allowing its use in thin-wall casting applications.UHPC is an ultra-high-strength cement-based material with high strength, high toughness, and low porosity. Its configuration principle is: by improving the fineness and activity of the component, without using coarse aggregate, the pores and micro-cracks in the material are minimized to obtain ultra-high strength and durability.

GFRC is a lightweight, durable material that can be cast into nearly unlimited shapes, colors and textures. There are two basic processes used to fabricate GFRC – the Spray-Up process and the Premix process. The Premix process is further broken down into various production techniques.

such as spray premix, cast premix, pultrusion and hand lay-up. GFRC is primarily used as an exterior facde or cladding material for both new construction and for recladding or restoration of existing building facades.

For these applications, the Spray-Up process is generally used and the GFRC “skin” is panelized on a steel stud frame and weighs 20-25 lbs. per square foot (97-122 kg/sq.m) Due to its extreme flexibility in design and function, it is also used extensively in applications not requiring a steel stud frame and is generally produced using one of the Premix processes.

These applications include architectural ornamentation (column covers, cornices, window and door surrounds, etc.), terra cotta restoration and replacement, fireplace surrounds, concrete countertops, faux rocks and planters. Without the frame, GFRC will weigh 7-10 lbs. per square foot (34- 48kg/sq.m)

  • • Highly durable and safe
  • • Design freedom since GFRC is able to be molded into almost any shape and color/texture
  • • Requires very low maintenance
  • • Installation is quick and cost effective
  • • Weather and fire resistant
  • • Economical and lighter than precast concrete
  • • Energy efficient
