Usage

Sika® Fibermesh®-150 act mechanically by supporting the aggregate within the concrete with multidimensional fiber network and developing a uniform bleed system.  The fiber does not affect the curing process chemically and does not absorb water.  The Sika® Fibermesh®-150 can be used in all types of concrete applications to control plastic shrinkage and settlement cracking.  Typical applications include:
  • Slabs on ground
  • Residential applications: side-walks, driveways, decks, curbs
  • Precast elements,
  • Overlays / toppings
  • Stucco
  • Shotcrete
  • Roads / Pavements
  • Bridge Decks
 

Advantages

  • Reduces plastic shrinkage cracking

  • Enhances durability
  • Promotes uniform bleed and reduces bleed water
  • Inhibits and controls the formation of intrinsic cracking in concrete
  • Increases cohesion and reduces segregation
  • Reinforces against abrasion
  • Reduces freeze/thaw damage

Packaging

Sika® Fibermesh®-150 fibers are available in 1 kg bags. The bags are packed into cartons and palletized.

Application

Application Information

Dispensing

Sika® Fibermesh®-150 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® Fibermesh®-150 at the normal recommended dosage rate does not require any mix design or application changes.  The fiber concrete can be mixed, sprayed or placed using conventional equipment.

Tooling & Finishing

Sika® Fibermesh®-150  can be finished by most finishing techiques as indicated in ACI-302.
Consumption

Recommended dosage

The dosage of the Sika® Fibermesh®-150 will vary according to the type of application and performance requirements.  Standard recommended dosage ratio of Sika® Fibermesh®-150 is between 0.5 - 0.9 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.
