Reinforced concrete

Hanson Fibrecrete

A range of fibre reinforced concrete

Hanson Fibrecrete is a range of fibre reinforced concrete. It incorporates fibre technology, added at the batching plant to enhance concrete performance and durability.

Plastic fibre concrete (structural)

Structural fibres (plastic) are manufactured from a high-strength, high modulus synthetic plastic. They are designed to replace welded mesh and light reinforcement bars.

Where to use it

  • Suspended floors and roof elements
  • Large scale industrial floors
  • Lightweight applications
  • Architecturally sensitive buildings
  • Complex, geometric elements

Benefits

  • Reduced overall construction cost over steel
  • Reduced manual handling and placement time (no steel fixing)
  • Increased crack control
  • No associated corrosion issues
  • Eliminates concern associated with correct placement of reinforcement and correct cover
  • Reduced structural weight (suspended slabs/roof elements)

Steel fibre concrete (structural)

Structural fibres (steel) are manufactured in various grades, deformations and sizes to suit most concrete flooring applications.

Where to use it

  • Heavily trafficked industrial paving (scrap yards)
  • Industrial ground bearing slabs
  • Jointless ground bearing slabs
  • Suspended slabs on piles
  • Impermeable concrete slabs

Benefits

  • Reduced overall construction cost over steel
  • Reduced manual handling and placement time (no steel fixing)
  • Increased crack control
  • Eliminates concern associated with correct placement of reinforcement and correct cover
  • Increased surface abrasion resistance

NOTE: Where either plastic or steel fibres are used as either a partial or total replacement to conventional steel reinforcement, we recommend that the structural designer is consulted

Polypropylene fibre concrete (non-structural)

Non-structural fibres are not an admixture, they are classified as an addition. They can be added to almost all conventional concrete mixes. Concrete mixes incorporating fibres comply with current European and British standards and require no additional specification criteria.

Where to use it

  • Concrete slabs/external paving
  • Deep sections >500mm
  • Strip footings and foundations
  • Concrete elements with a high length to width ratio (e.g. pathways/kickers) the majority of concrete will benefit from fibre addition

Benefits

  • Reduced shrinkage (less crack potential)
  • Increased resistance to freeze thaw damage when used with a conventional air entraining agent
  • Reduced potential for settlement cracking
  • Reduced risk of delaminating
  • Increased surface durability

Sustainable solution

Hanson can incorporate a high proportion of Hanson Regen, a cement replacement material that generates a much lower level of CO2 emissions than ordinary cement, minimising environmental impact. Recycled aggregates can also be incorporated subject to local availability and mix design.

Benefits subject to good concreting practice (placement, finishing and curing).
