AR Glass Fibre Spray Roving (ZrO2>16.7)

What is alkali-resistant glass fibre:

Alkali-resistant glass fibre is the rib material of glass fiber reinforced (cement) concrete (GRC), it is 100% inorganic fiber and an ideal substitute for rolled steel and asbestos in non-load-bearing cement components. Alkali-resistant glass fiber is characterized by high alkali resistance, it can effectively resist the erosion of high alkali substances in cement. Besides, it has high bond stress and extremely high elasticity modulus, shock resistance, tensile strength and bending strength. The material is non-combustible and has high resistance against frost and changes in temperature and humidity. Meanwhile, it has excellent crack-resistance and anti-permeability performance as well as strong designability. Moreover, it is easily shaped up. Alkali-resistant glass fibre is a new type of environmentally friendly reinforced material widely used in high-performance reinforced(cement) concrete.

For example:ARC13-2700H
AR:Alkali Resistant
C: Continuous fiber
13:Mono-filament diameter, unit μm
2700:Roving linear density, tex
H:Zirconium oxide content: 16.7%

AR Glass Fiber Advantages

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.

SuperFiber AR Glass 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.

SuperFiber AR Glass 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.


SuperFiber 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. 

SuperFiber spray roving is used to produce GRC components by manual spray application technique or by automation process. It is applicable to the reinforcement of ordinary portland cement. Based on the reinforced strength, the product has excellent long-term strength performance and is designed to achieve the optimal production capacity. It is used to produce GRC wallboard and other building components as well as the components of civil engineering and infrastructure.

How it works

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.

SuperFiber AR Glassfibre roving’s are used for spraying with industry standard GRC spray equipment. The normal recommended dosage is 5% by weight.


18±1kg/roll,individually shrunk film packaging (with weight tag); Each fumigated pallet has 3 or 4 layers with 16 rolls/ layer,48 rolls/small pallet , 64 rolls/big pallet.

It loads 20 pallets (Small & big pallet stacked in 2 layers) per 20 feet container, with a net weight 20 tons.

The product shall be stored in the original package to keep internal dry. It is best to store it at 15℃-35 ℃ and in relative humidity of 35%-65%. If the product is stored at low temperature (below 15℃), it is better to store it in the manufacturing shop for 24 h before use to prevent condensation.
