Synthetic Fibre

01 Overview

Synthetic fibers refer to fiber materials produced through chemical synthesis, with common examples including polypropylene fibers and polyester fibers. These synthetic fibers are incorporated into concrete to enhance its performance. They improve the tensile strength, crack resistance, and toughness of concrete, thereby playing a positive role in extending its service life.

Synthetic fibers are commonly used as reinforcement in concrete to improve its properties, such as crack resistance, durability, and impact strength. They are an alternative or supplement to traditional steel reinforcement, offering several advantages like corrosion resistance, easier handling, and faster installation.

Types of Synthetic Fibers used in Concrete:

  1. Polypropylene Fibers:
    • Most common synthetic fibers used in concrete.
    • Help control plastic shrinkage cracking.
    • Improve impact and abrasion resistance.
    • Do not corrode.
  2. Polyacrylonitrile Fiber:
    • Provide good flexibility and toughness.
    • Used for crack control and as a supplementary reinforcement.
  3. Polyethylene Fibers:
    • Have high tensile strength.
    • Improve fracture toughness and durability.

02 Benefits of Synthetic Fibers

  • Reduce shrinkage cracking during the plastic and hardened state.
  • Increase toughness and impact resistance.
  • Improve post-cracking behavior by bridging cracks.
  • Resistance to corrosion (unlike steel fibers).
  • Enhance the overall durability and lifespan of concrete structures.

Application:

  • Mixed directly into the concrete during batching.
  • Dosage typically ranges from 0.1% to 2% by volume, depending on the desired effect.
