The world's foremost resource on decorative concrete
The popularity of glass-fiber reinforced concrete (GFRC) has grown in the past few years as more and more people discover its versatility, strength and relative ease of manufacture. GFRC makes it possible to create stronger and lighter elements and complex 3-D pieces easily.
Compaction of each thin layer of backer is a critically important step in the fabrication of GFRC.
In suburb located northwest of Denver a new park sits on 9 1/2 acres of open land across from its city hall. Built to give the community a gathering spot where children could play and families could stroll, take in art and view live performances.
Born out of frustration with the long learning curve for mastering GFRC, Cheng Concrete’s NeoMix D-FRC is designed to not only shorten that learning curve for contractors, but also to outperform traditional GFRC in regards to flexural strength and abrasion resistance.
GFRC is a combination of fine aggregate, cement, water, polymer, chemical admixtures and glass fiber. The key to GFRC is the glass-fiber reinforcement. The fibers take the place of steel in a wet-cast mix. They allow GFRC to develop much higher flexural strengths than typical wet-cast concrete, allowing you to cast thinner, lighter sections and pieces.
The Montego is a three-story condominium building in Oceanside, Calif., that offers roof access for its residents to relax or entertain. The building is a couple of blocks from Oceanside Pier, so the rooftop overlooks the beach. Sounds idyllic, right?
This sleek S-curve, cast by Nick Relampagos using glass-fiber reinforced concrete, is embedded with radiant heating. Just turn it on and it gently warms you from beneath as the sun shines down from above.
Thanks to its incorporation of glass fibers into mix design, GFRC is thinner, lighter, stronger and offers more design flexibility.
In this article you will see how to properly apply your GFRC mix to your created forms once you’ve prepared it.
Let’s start at the beginning: What is GFRC, what are its benefits and what are its downsides? GFRC stands for glass-fiber reinforced concrete. The GFRC I use is a composite of portland cement, silica sand, Forton VF-774 , Liquefaction Compound, Vitro Minerals VCAS-micronHS, water, and alkali-resistant chopped glass-fiber strands.
