Sika® Fibermesh® AC

MICRO MONOFILAMENT ACRYLIC FIBER

Sika® Fibermesh® AC is a new generation of micro monofilament acrylic fiber for use in concrete. Sika® Fibermesh® AC is specifically designed for the purpose of controlling plastic shrinkage and settlement cracking.

  • Higher fiber count per pound than standard monofilament fibers.
  • Virtually invisible in concrete.
  • Allows for lower dosage compared to other monofilament types of fiber.
  • Reduces the formation of plastic shrinkage cracking in concrete.
  • Provides multi-dimensional reinforcement.
  • Improves impact, shatter and abrasion resistance.
  • Enhances durability and toughness of concrete.
  • Reduces bleeding.
  • Excellent finishability

Usage

Sika® Fibermesh® AC act mechanically by supporting the aggregate within the concrete with multidimensional ultra fine 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® AC can be used in all types of concrete applications to control plastic shrinkage and settlement cracking.  Typical applications include:
  • Residential or commercial slabs on ground
  • Slab on ground overlays,
  • Precast applications,
  • Stucco,
  • Shotcrete
  • Architectural concrete
 

Advantages

  • Higher fiber count per pound than standard monofilament fibers.
  • Virtually invisible in concrete.
  • Allows for lower dosage compared to other monofilament types of fiber.
  • Reduces the formation of plastic shrinkage cracking in concrete.
  • Provides multi-dimensional reinforcement.
  • Improves impact, shatter and abrasion resistance.
  • Enhances durability and toughness of concrete.
  • Reduces bleeding.
  • Excellent finishability

Packaging

Sika® Fibermesh® AC fibers are available in a variety of packaging options.  The bags are packed into cartons and palletized.

System information

Compatibility

Use of Sika® Fibermesh® AC with some polycarboxylate based admixtures may cause an increase in air content within the concrete. Trial mixes must be conducted to verify the affect of using SikaFiber® AC 100 along with these admixtures on the air content of concrete.

Application

Application Information

Mixing

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

Recommended Dosage

The dosage of the Sika® Fibermesh® AC will vary according to the type of application and performance requirements.  Standard recommended dosage ratio of Sika® Fibermesh® AC is between 0.5 - 1.0 lbs/cu yd (0.3 - 0.6 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
