Glass Fiber Reinforced Concrete
HD-GFRC®
High Density - Glass Fiber Reinforced Concrete
At Formeffects, we have formulated a High Density GFRC mix specifically designed to provide superior performance for cladding applications. GFRC is the result of mixing a combination of cement, sand, admixtures, water, and glass fiber reinforcing. Common GFRC formulations result in a density of 105lbs/cf, while our HD-GFRC mix has a density of 138lbs/cf. The 30% increase in density is the result of careful engineering to minimize particle sizing throughout the mix matrix and the water ratio to create a tightly packed concrete. The densely packed HD-GFRC mix provides superior performance in important attributes for cladding applications.
Double Layer Mesh
At Formeffects, we use a combination of premixed glass fiber reinforced strands and two layers of glass fiber scrim mesh in our precast panels. The premix fibers disperse themselves in a random orientation, so not all the fiber strands are being utilized to their full reinforcing potential.
Scrim mesh is a structured form of reinforcing, utilizing continuous parallel and 90 degree perpendicular strands. The mesh is laid into the mix during casting in plane to the faces of the concrete panel to provide a highly efficient means of reinforcing.
The end result is stronger and more durable concrete panel.
