Sika® Confibre® 19F

Fibrillated Polypropylene Fibre

Sika® Confibre® 19F is a fibrillated polypropylene fibre for use in concrete.

Sika® Confibre® 19F provides the following benefits:
  • Increased resistance to plastic shrinkage cracking
  • Increased impact resistance
  • Increased abrasion resistance
  • Increased cohesion
  • Non staining
When used in shotcrete the benefits are:
  • Reduced rebound
  • Thicker layer builds
  • Reduced sag

Usage

Sika® Confibre® 19F Is used in concrete to increase the strain capacity of the fresh concrete, thereby, reducing the incidence of plastic shrinkage cracking. Is typically used in concrete for the following applications:
  • Floor slabs
  • Driveways
  • Tilt slabs
  • Floor toppings
  • Precast elements
  • Coloured concrete
Can be used in both dry and wet shotcrete applications for:
  • Pools
  • Channels
  • Retaining walls
  • Building restoration

Consumption

Recommended dosage

The recommended minimum dose rate of Sika® Confibre® 19F is 0.9kg (1 bag) per cubic metre of concrete.

Optimum dosage depends on the type of concrete, site conditions, mix proportions and desired plastic and hardened concrete properties. Laboratory and/or field trials are essential in determining the optimum dosage.
