GFRC
Glass fibers make this reinforced concrete lighter and slimmer for use in architecture and furniture
GFRC stands for glass fiber reinforced concrete. Reinforced concrete typically has steel rods and mesh that give the material tensile strength (concrete is good in compression, not tension). But GFRC has glass fibers instead of steel, meaning the concrete — typically facade panels in architectural applications — is lighter and slimmer in profile. GFRC is also used for precast furniture, taking advantage of the same qualities.
This housing development in Zurich has GFRC panels on the exterior. The lightweight panels mean that the structure required to support them can be smaller.
The texture of the panels is another trait that comes from the GFRC, which, as we'll see, offers diverse sculptural possibilities.
The planter bases for this bench are made from GFRC, which is strong enough to support the bench but light enough to be made offsite and to sit on the wooden deck.
Concrete Bench
Here is another piece of furniture made with GFRC. The "plantable cracks," as the manufacturer calls them, are a unique touch that the material affords.
