Owens Corning’s Anti-CRAK 12mm HD AR Fibres are a high-performance glass fibre solution designed to reinforce concrete—particularly in Glass Fibre Reinforced Concrete (GFRC) applications. Engineered to control and prevent cracking in fresh concrete, Anti-CRAK HD AR Fibres offer a versatile, cost-effective alternative to traditional steel reinforcement. With a robust dispersion rate of 220 million filaments per kilogram, these fibres are easily integrated into concrete mixes, ensuring excellent workability and an invisible finish on the cured surface.

Key Features & Benefits

1. Increased Strength & Durability
   • Enhanced Crack Resistance: Controls micro-cracking in fresh concrete, reducing long-term structural issues.
   • Superior Bending & Impact Strength: Fibre glass composition resists bending, deformation, and everyday wear.
2. Lightweight Reinforcement
   • Easier Handling & Transport: Fibre glass is significantly lighter than steel, minimizing the load on foundations and simplifying logistics.
   • Reduced Structural Loads: Ideal for projects where weight reduction is a priority, such as retrofit or high-rise structures.
3. Flexible Design & Aesthetics
   • Thinner & Complex Shapes: Enables GFRC to be molded into intricate details or slender profiles without compromising strength.
   • Invisible Finish: Anti-CRAK HD AR Fibres do not protrude through the surface, eliminating extra finishing procedures.
4. Corrosion Resistance
   • Long-Term Performance: Unlike steel, glass fibres do not rust, ensuring durability in moist or corrosive environments.
   • Sustainable & Environmentally Friendly: Free from harmful emissions and fully recyclable, contributing to greener construction practices.
5. Cost-Effectiveness
   • Lower Material Costs: Fibre glass often costs less than steel, making GFRC more affordable to produce.
   • Reduced Maintenance: Longer service life and minimal corrosion decrease the need for repair or replacement.
6. High Dispersion & Workability
   • 220 Million Filaments per kg: Assures even distribution throughout the concrete mix, improving consistency and performance.
   • Easy Mix Integration: Simple to incorporate using standard batching methods—no special tools required.

Performance Highlights

• Corrosion-Free: Ideal for structures exposed to moisture, salt, or chemical agents.
• Thermal Expansion Compatibility: Fibre glass handles thermal stress without cracking, maintaining the integrity of decorative or thin-walled elements.
• Invisible on Finished Surfaces: Improves aesthetics and reduces labor on additional finishing steps.

Recommended Uses

1. Glass Fibre Reinforced Concrete (GFRC)
   • Architectural panels, facades, and decorative elements that benefit from lighter weight and intricate shapes.
2. Precast & Prefabricated Elements
   • Balusters, columns, countertops, and more, where reducing concrete thickness without losing strength is crucial.
3. Renovation & Retrofit Projects
   • Ideal where added load from traditional steel reinforcement must be minimized.
4. Outdoor & Marine Environments
   • Retaining walls, landscaping features, and seaside installations that demand high corrosion resistance and long-term durability.
5. High Aesthetic Demands
   • Complex shapes and textured surfaces, where fibre invisibility improves surface quality without extra finishing.
