SikaFiber® Force-50

Polyolefin macro fibres for concrete

SikaFiber® Force-50 are 50 mm long polyolefin macro fibres for use in structural concrete

General
  • Packaged in soluble bags for easy dosing
  • Provides better cohesion of the fresh concrete
  • Dissipates strains in concrete and prevents structural cracking
  Improves characteristics of hardened concrete
  • Crack bridging capacity
  • Higher flexural and shear strength
  • Improves loading capacity and ductility
  • Increases abrasion resistance
  • Increases resistance to freeze thaw attack
Fibres in reinforced concrete
  • Reduces or eliminates the amount of steel reinforcement
  • Easier to handle than reinforcement bars and meshes
  • No need for cutting or tying
  • Reduces construction time
  • Homogeneously embedded throughout concrete matrix
  • Fills edges, corners and difficult shapes
Compared to steel fibres
  • No corrosion stains on surface
  • Greater displacement capacity due to higher stresses

Usage

For most types of in-situ cast structural concrete to reduce the amount of steel reinforcement, distribute stresses, increase structural properties or increase abrasion and fire resistance:
  • Ground bearing slabs
  • Precast concrete elements
  • Foundations
  • Building and infrastructure structural components

Technical Information

Concreting guidance

The standard rules of good concreting practice, concerning production and placing must be followed. Laboratory trials must be carried out before concreting on site, especially when using a new mix design. Fresh concrete must be cured properly and curing applied as early as possible.

Concrete Mixing Time

Extend the normal mixing time to ensure a homogeneous distribution of fibres in the concrete mix. This particularly applies to high fibre dosages (>5 kg/m3)

Tensile Strength

~450 N/mm2 (MPa)

(EN 14889-2)

Application

Application Information

Compatibility

Compatible with other Sika admixtures      

Dispensing

Add the fibres in the concrete mixer with the dry aggregates taking care to evenly distribute the fibres throughout the mix.

The fibres can be added when all the mix components have been added either in the concrete mixer or truck mixer. Mixing time will need to be increased to ensure a uniform fibre distribution (as a guide add 1 extra minute for every 1m3). Do not add the fibres directly into the mixing water.
Consumption

Recommended Dosage

3–6 kg/m3
