Alkali Resistant Glass Fiber Reinforced Concrete Chopped Strands

Introduction of Alkali-resistant Glass Fiber

Alkali-resistant glass fiber is the rib material of glass fiber reinforced concrete (GRC for short). It is 100% inorganic fiber and is an ideal substitute for steel and asbestos in non-load-bearing cement components. Alkali-resistant glass fiber is characterized by good alkali resistance, can effectively resist the erosion of high-alkali substances in cement, strong bond strength, extremely high elastic modulus, impact resistance, tensile strength, and flexural strength, non-flammability, frost resistance, temperature and humidity change resistance, excellent crack resistance and impermeability, strong designability and easy molding. Alkali-resistant glass fiber is a new type of green and environmentally friendly reinforcement material widely used in high-performance reinforced concrete.

Function of Alkali-resistant Glass Fiber

1. Improve the flexural properties of hardened concrete.

2. Control and prevent cracking of fresh concrete, hardened concrete and mortar (plastic shrinkage cracking, shrinkage and thermal shrinkage cracking, and load cracking).

3. Evenly mixed and high efficiency. Not easy to corrode.

4. Good pumping performance. Low water consumption.

5. High doses do not affect process performance

FAQs of Alkali-resistant Glass Fiber

Q: Why is alkali-resistance important in glass fibers?

A: Alkali-resistance is crucial because standard glass fibers can degrade when exposed to the highly alkaline environment of concrete, leading to a loss of strength over time. AR glass fibers maintain their integrity and performance in such environments, ensuring long-term durability.

Q: What are the typical components of alkali-resistant glass fiber?

A: AR glass fibers are typically composed of a base glass formulation that includes additives such as zirconia (ZrO₂), alumina (Al₂O₃), or calcia (CaO) to improve resistance to alkali attack. The exact composition can vary depending on the manufacturer and specific application requirements.

Q: How is alkali-resistant glass fiber manufactured?

A: The manufacturing process involves melting a mixture of raw materials to form a glass, which is then cooled and drawn into fine fibers. The composition is specifically engineered to resist alkali attack. The fibers are often coated with a sizing that further improves compatibility with matrix materials and enhances handling.

Q: Can alkali-resistant glass fiber be recycled?

A: The recyclability of AR glass fiber depends on the specific composition and the condition of the fiber after use. While glass itself is theoretically recyclable, the presence of additives and coatings may complicate the recycling process. Specialized recycling processes may be necessary to reclaim the glass content.
