Alkali resistant glassfibr advantages

With the original E-glass fibers, durability was a big issue since the fiber broke down and lost strength in concrete, then the alkali-resistant Glassfibre is developed and made resistant to the high alkali corrosion through the use of zirconium-dioxide.

Huierjie ARG Fiber properties including excellent alkali -resistance with high ZrO2 content of over 16.7% , good tensile & flexural properties, high elastic modulus, freeze thaw resistance and crack fatigue with excellent impermeability properties.

Huierjie ARG Fiber used in the manufacturing of GRC cladding provides enough opportunities for architects to design ornate and complex exterior high performance & environmentally friendly building cladding solutions.

Application:

Spray-up is similar to shotcrete in that the fluid concrete mixture (minus ARG fibers) is sprayed into the forms. The concrete is sprayed out of a gun-like nozzle that also chops and sprays a separate stream of long fibers. The concrete and fibers mix when they hit the form surface. ARG fiber is fed off of a spool in a continuous thread into the gun, where blades cut it just before it is sprayed. Chopped fiber lengths tend to be much longer (about 1.5") than fibers that get mixed in, since long fibers would ball up if they were mixed into the concrete before spraying.
