MICRO-SYNTHETIC FIBRE

Sika® Fibercast®-500, micro-reinforcement system for concrete is 100 percent virgin homopolymer polypropylene fibres containing no reprocessed olefin materials. Specifically engineered and manufactured in an ISO 9001 certified manufacturing facility for use as reinforcement for concrete applications.  Sika® Fibercast®-500 was previously Fibercast 500.

  • Increases cohesion and reduces segregation
  • Inhibits and controls the formation of intrinsic cracking in concrete
  • Reduces plastic shrinkage and settlement cracking
  • Reinforces against the effect of shattering forces
  • Reinforces against abrasion
  • Reduces freeze/thaw damage
  • Inhibits water migration
  • Permits thicker layer per passing of sprayed concrete
  • Reduces rebound and material waste in sprayed concrete
Usage
Sika® Fibercast®-500 act mechanically by supporting the aggregate within the concrete with multidimensional fibre network and develops a uniform bleed system.  The fibre does not affect the curing process chemically and does not absorb water.   Typical applications include:
  • Precast
  • Hazardous material storage
  • Septic tanks
  • Stucco
  • Agricultural products
  • Tanks and storage
  • Marine products
  • Walls
  • Shotcrete
