Sika® Fibercast®-500

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

Application Information

Dispensing

Sika® Fibercast®-500 in degradable bag can be added directly to the concrete mixing system after the batching of the other ingredients and mixed for 4 to 5 minutes or 70 revolutions. 

Application

The addition of Sika® Fibercast®-500 at the normal recommended dosage rate does not require any mix design or application changes.  The fibre concrete can be mixed, sprayed or placed using conventional equipment.

Tooling & Finishing

Sika® Fibercast®-500  can be finished by most finishing techiques as indicated in ACI-302.
Consumption

Recommended Dosage

The dosage of the Sika® Fibercast®-500 will vary according to the type of application and performance requirements.  Standard recommended dosage ratio of Sika® Fibercast®-500 is between 0.9 to 1.8 kg/m3 of concrete.  Dosages outside the recommended dosage range can be used to meet project specific requirements.  If this is the case please contact your Sika representative for technical support.
