USA PCI Standard AR Glassfibre roving for GRC

AR GLASSFIBRE ROVING - HEJ 16.7%

HEJ 16.7% is an alkali resistant glass fibre roving (ZrO2>16.7) designed for use in all kinds of GRC exterior cladding panels and composites using the spray applied production method.

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.
