Fibre-reinforced concrete (FRC) is concrete containing short, discrete fibres that are uniformly distributed and randomly oriented throughout the mix. These fibres enhance the concrete’s structural integrity by improving its post-crack behaviour and resistance to various stresses.
Types of fibres used:
- Steel fibres (for structural applications)
- Synthetic/polymer fibres (for crack control)
- Glass fibres (for architectural elements)
- Natural fibres (for specific applications)
Benefits:
- Enhanced toughness and impact resistance
- Improved crack control and reduced crack width
- Increased fatigue resistance
- Better resistance to plastic shrinkage cracking
- Reduced permeability
FRC is commonly used in industrial floors, pavements, tunnel linings, precast elements, and applications requiring enhanced durability.
