GFRC (Glass Fiber Reinforced Concrete) is lighter, stronger, faster than normal concrete. GFRC pieces can be de-molded as early as 24 hours. This Expressions-LTD Basic GFRC Mix recipe works great for GFRC countertops, sinks, and furniture pieces.

Gaining flexural strength from glass fibers, GFRC is capable of being made in much thinner sections than traditionally cast concrete, while having improved flexural strength. GFRC can be sprayed into the molds, forcing out the air and producing a dense and tight finish. GFRC can also be directly cast into molds in certain applications.
Introduction to GFRC (Glass Fiber Reinforced Concrete)
Mix design isn’t a concept that can be tackled in one blog post, but here are some of the basic components in a good GFRC mix: Fine Sand – Sand used in GFRC should have an average size passing a #50 sieve to #30 sieve (0.3 mm to 0.6mm).
GFRC Preblended uses all white ingredients, naturally curing to a bone white. The mix can be pigmented with any of the Buddy Rhodes Color Wheel™ color collections. The mix has all the necessary high-performance ingredients preblended, including curing polymer, such that only water and necessary reinforcement need to be added.
Our GFRC Preblended Concrete Mix can be sprayed, poured, pressed, or troweled. Fibers are not preblended into our GFRC mix, so that you can select the fiber combination and load rate that suits your needs. There are also no larger aggregates in the mix, m
With its high cement content and low water-cement ratio (0.33 to 0.38), GFRC can dry out quickly and not gain full strength. Traditionally, GFRC panels were cured in a moist-room for 7 days. Today, more commonly, this is overcome by using an acrylic polymer additive which serves as a curing compound to prevent the mix water from evaporating.
Jun 19, 2008 · GFRC stands for glass-fiber reinforced concrete. The GFRC I use is a composite of portland cement, silica sand, Forton VF-774 (an acrylic admixture), Liquefaction Compound (a dry plasticizer specifically formulated by my team for use in GFRC), Vitro Minerals VCAS-micronHS (a pozzolan that adds strength and helps to decrease porosity), water ...
A typical mix with 5% glass fiber has a compressive strength of 6,000 to 8,000 psi. GFRC Durability. Glass fiber reinforced concrete has been tested both by accelerated aging tests in the laboratory and in real life installations. GFRC can be expected to last as long as pre-cast concrete.
Manufacturing of GRC | Glass Reinforced Concrete | GRCA
Glassfibre Reinforced Concrete (GRC), also known as Glass Fiber Reinforced Concrete (GFRC) is generally manufactured by either the "sprayed" process or the "premix" process. Premix GRC can either be vibration compacted, or manufactured using a self compacting GRC mix.
The mix should contain enough water to achieve the required consistence. Consistence may be assessed by eye or measured by carrying out a slump test (SABS Method 862-1: 1994) A mix made according to this table, and to the required consistence, should be assessed for workability and stone content before being used on a large scale.
