Alkali Resistant Fiber (AR or ARG)

Alkali Resistant Fiber (AR or ARG) – is resistant to alkaline environment of water reactive cement. The higher the content of zirconium in the glass fibers, the better the resistance to the effects of alkaline hydration products of Portland cement it has . They have completely replaced carcinogenic asbestos fibers.

Glass Fiber Reinforced Concrete, GRC or GFRC

Glass Fiber Reinforced Concrete, GRC or GFRC – is more stable and durable product than traditional architectural and structural concrete. In the first phase of production, the glass fibers are added in order to eliminate or limit the shrinkage cracking occurring mainly in components of the concrete pavement, plasters and sprayed layers of mortar repair. They act in the early stages of concrete ripening, similar to commonly used polypropylene fibers (PP). Glass fibers , in contrast to the polypropylene fibers (PP) have a nature of reinforcing fibers, because their module of elasticity is much higher than the elastic modulus of concrete. For comparison, the Young’s polypropylene fibers (PP) module of elasticity is much lower and amounts to only 5 GPa, yet the glass fibers allow to obtain a Young’s modulus at 25 GPa level.

Composition of the GRC concrete (GFRC)

Linings and facade panels, are Non-load bearing elevation panels, fixed to the structure by means of bonding systems. An insulating layer may be placed between the plate and the support structure (for PN-EN 14992:2007), available dimensions of the facade panel and lining are:

  • 100 x 50 cm
  • 120 x 80 cm
  • 240 x 120 cm
  • 200 x 400 cm
  • and higher, depending on design and specifications.
