Macro Synthetic Fibre

Macro Synthetic Fiber for Concrete Reinforcement

Macro Synthetic Fiber is a high-performance, engineered fiber designed to provide superior reinforcement in concrete, shotcrete, and precast applications. These Fibers are made from 100% virgin polypropylene or a blend of synthetic polymers, offering an ideal alternative to traditional steel reinforcement and steel mesh. Macro synthetic fibers are increasingly used in industrial flooring, tunnel linings, precast elements, and infrastructure projects due to their excellent mechanical performance, durability, and Corrosion Resistance.

Key Features and Benefits

• High Tensile Strength: Macro synthetic fibers possess high tensile properties, enabling them to control cracking and improve the post-crack performance of concrete.

  Corrosion-Resistant: Unlike Steel Fibers or mesh, macro synthetic fibers do not corrode, making them ideal for use in harsh environments, marine structures, and de-icing salt exposure areas.

• Enhanced Durability: These fibers significantly increase impact resistance, fatigue strength, and abrasion resistance of concrete structures.

• Time and Cost Savings: By eliminating or reducing the need for steel mesh, macro synthetic fibers help lower labor costs and simplify concrete placement.

• Three-Dimensional Reinforcement: Dispersed uniformly throughout the mix, macro synthetic fibers provide multidirectional reinforcement and increase concrete toughness.

• Compliant with International Standards: Most macro synthetic fibers meet ASTM C1116, EN 14889-2, and other global Concrete Fiber specifications.

Applications

Macro synthetic fiber is widely used across a range of applications:

• Industrial and Warehouse Floors

• Precast Concrete Products

• Shotcrete for Tunnels and Mining

• Bridge Deck Overlays and Pavements

• Water Retaining Structures

• Airport Runways and Taxiways

• Concrete Roads and Highway Pavements

Advantages Over Steel Fiber

Compared to steel fiber, macro synthetic fiber is lightweight, non-magnetic, and easier to handle. It does not interfere with equipment or pose injury risks during installation. Additionally, it offers consistent performance without the risk of rust or surface spalling, especially in freeze-thaw environments.

Sustainable Building Material

Macro synthetic fiber contributes to sustainable construction by reducing the need for traditional reinforcement, decreasing carbon emissions related to steel production, and enhancing the long-term performance of concrete, thus lowering maintenance needs.
