1. Characteristics of AR glass fiber roving

What is AR glass fiber roving? Alkali-resistant glass fiber roving contains 16.7% zirconium and is designed for reinforcing cement-based materials. It has excellent alkali resistance and good dispersibility. Compared with ordinary glass fiber, alkali-resistant yarn can effectively prevent performance degradation in alkaline environment, improve product service life and structural stability, and is widely used in GRC (glass fiber reinforced cement), building curtain walls, prefabricated components and other fields. Its core features are as follows:

16.7% high zirconium content, excellent alkali resistance

Good dispersibility and wettability, significant reinforcement effect

Highly compatible with cement system, not easy to corrode

Enhance the crack resistance and overall structural strength of cement products

2. Advantages of AR glass fiber roving

Extend the life of cement products, anti-aging and corrosion resistance

Enhance the crack resistance, toughness and impact resistance of GRC product

Reduce weight and improve the safety of building structures

Better cost and simple construction

3. Application scenarios

GRC curtain wall panels, decorative components

Cement pipes, manhole covers, cable troughs

Municipal landscape products

Building exterior walls, fences, prefabricated components

4. Selection guide

Fiber diameter: commonly 13 and 15 microns

Linear density: 2400tex、2700tex, etc.

Zirconium content: 16.7%

5. FAQ

Why do GRC or cement products use AR glass fibers?

Ordinary glass fibers are easily corroded over time in an alkaline environment such as cement, and their strength will drop rapidly. AR glass fiber contains 16.7% zirconium oxide, which can effectively resist alkaline corrosion and maintain the reinforcement effect for a long time, making it more suitable for GRC and cement products.

Is the AR glass fiber already impregnated with resin?

No. AR glass fiber is generally shipped as dry yarn with a special alkali-resistant impregnant on the surface to facilitate bonding with cement. The final impregnation and reinforcement effect is achieved through your premixing, spraying and other processes and cement reaction.

What is the relationship between AR glass fiber and GRC products?

GRC is the abbreviation of Glassfiber Reinforced Cement. GRC is to add AR glass fiber to ordinary cement to play a reinforcing role, prevent cement products from cracking and deformation, and improve overall toughness and service life. The GRC industry itself relies on alkali-resistant glass fiber as a reinforcing material. It can significantly improve the crack resistance, toughness and durability of cement products. If there is no alkali-resistant glass fiber, the alkalinity in the cement can easily corrode the fiber, and the product will easily crack and age over time. Therefore, the GRC industry uses AR glass fiber with 16.7% zirconium content, which is almost the industry default standard.

6.Summary

AR glass fiber roving (16.7% zirconium content) has become an indispensable core material in the GRC industry due to its excellent alkali resistance and outstanding reinforcement performance. It can not only significantly improve the strength, toughness and durability of cement products, but also help various construction fields to create lighter, more beautiful and durable products.
