Synprop® Concrete Reinforcing Fibres

Synprop® Concrete Reinforcing Fibres

Garstan manufactures macrofibres for the civil engineering and concrete industry. Our Synprop® Concrete Reinforcing Fibres are wrapped in water soluble film, and packed into water soluble  boxes to allow for easy dosing, or clear plastic bags.

What is Synprop® Concrete Reinforcing Fibres and how will it benefit me?

Synprop® Concrete Reinforcing Fibres is an innovative product, and its popularity is quickly gaining traction worldwide. It is a polypropylene fibre, that has a continuous deformed profile. Its “X” shape anchorage is specifically designed for Shotcrete, normal pouring methods, mining, tunnelling and various other applications as opposed to the conventional rebar or welded mesh. Concrete is a cost effective and versatile construction material, yet it is also beset with a number of drawbacks that are inherent to its composition. By accepted engineering standards, concrete is relatively brittle and lacks flexural strength. Concrete also has the propensity to crack in both its plastic (early-age) and hardened (long-term) state. In either cases, these cracks can jeopardize the overall integrity of the concrete and not allow it to maintain its maximum performance capability. Fibre reinforcement stands out from other reinforcing products through its ability to make concrete more pliable, and therefore it offers ultimate flexibility in the design and construction process. Working with fibre reinforcement not only means less steel, but it also eliminates and reduces the labour intensive process of steel fixing. Fibres are added directly to the concrete matrix and evenly distribute throughout. The result is an advanced, multi-dimensional reinforcement system that can be placed quickly, accurately and safely.

Primary fibre applications

  • Flooring (Slab-on- ground, both interior and exterior, commercial and light/medium/heavy industrial and warehouse slabs)
  • Exterior pavements
  • Overlays & Toppings
  •  Sidewalks/Driveways/Parking areas for malls / industrial / warehouse sites
  • Marine structures
  • Airport runways
  • Shotcrete – tunnel lining / irrigation ditches / slope stabilisation

Advantages of fibre reinforcing

  • Secondary reinforcement used as an alternative to welded mesh
  • Improved ductility and increased flexural toughness (residual strength)
  • Inhibits the formation of plastic shrinkage and plastic settlement cracking
  • Control of drying shrinkage and temperature cracking
  • Provides impact, abrasion and shatter resistance
  • Reduces water migration, bleedwater and permeability of concrete
  • Provides improved concrete durability and uniformly distributed reinforcement
  • Excellent finishing characteristics
  • Pump-able reinforcement
  • Typically more cost effective than traditional steel reinforcement
