Product Polypropylene Fibre Concrete

Product Description

Polypropylene fibre (short-cut strands of very fine denier monofilament*) is added to the concrete during batching. Thousands of individual fibres are then evenly dispersed throughout the concrete during the mixing process creating a matrix-like structure.

Properties

  • Improves concrete’s resistance to plastic shrinkage cracking.
  • Inhibits formation of micro-cracks due to dimensional change.
  • Reduces sedimentation.
  • Increased cohesion of the mix.
  • No requirement for crack control steel mesh.
  • Concrete placement and crack control in ONE operation.
  • Reduced bleeding.
  • Less expensive (per m2) than conventional steel mesh reinforcement.
  • Reduced plastic cracking means a reduction in surface permeability.
  • Bleed water control inhibits migration of cement fines and sand to the surface.
  • Even distribution of fibres throughout the concrete.
  • A tougher surface with fewer bleed hole.
  • Reduced plastic cracking means a reduction in surface permeability.
  • Bleed water control inhibits migration of cement fines and sand to the surface.
  • Even distribution of fibres throughout the concrete.
  • A tougher surface with fewer bleed holes.

Benefits

  • Reduced frequency of plastic cracking.
  • Improved durability and reduced permeability.
  • Decreases risk of plastic settlement cracking over re-bar.
  • Reduced settlement and easier finishing.
  • No delays to fast track schedule.
  • Easier positioning of joints.
  • No need to purchase and store additional material.
  • Reduced site labour requirement.
  • No secondary steel mesh is required and reinforcement is automatically positioned.
  • Easier finishing of the concrete surface.
  • Reduced project costs.
  • Enhanced durability.
  • Harder, more durable surface with better abrasion resistance.
  • Improved flexural properties.
  • Increased resistance to spalling at higher temperatures and so…. better fire resistance.
  • Reduced absorption of water, chemicals and dirt.

Application

  • Most small builder, cash sales and DIY applications
  • Internal floor-slabs (retail stores, warehouses, etc.)
  • External slabs (driveways, yards, etc.)
  • Agricultural applications
  • Roads, pavements, driveways, Kerbs
  • Shotcrete; thin section walling
  • Overlays, patch repair
  • Water retaining structures, marine applications
  • Security applications such as safes and strong rooms
  • Deep lift walls

How to use

  • The concrete can be compacted and finished normally. Trowelling embeds the fiber in the concrete surface.
  • Some fibers may be exposed where textured finish is applied, but these quickly disappear.
  • Batching fiber reinforced concrete - longer batch times.
  • Concrete with fiber can be pumped in most cases.
  • Control joints are necessary and should be spaced at normal intervals prescribed for an reinforced slab design.
