Sika® Fibermesh®-650

MACRO-SYNTHETHIC FIBER

Sika® Fibermesh®-650 is macro synthetic reinforcing fiber complying with ASTM C 1116, Type III. Sika® Fibermesh®-650 is 100% virgin copolymer fiber designed to provide a uniform three dimensional reinforcement system in the concrete mix.  Specifically engineered and manufactured in an ISO 9001 certified manufacturing facility. Sika® Fibermesh®-650 previously Fibermesh 650 or SikaFiber Force 650.

  • Reduces plastic shrinkage/settlement cracking and drying shrinkage cracking in concrete.
  • Provides multi-dimensional secondary reinforcement, alternate to welded wire fabric, light rebar and steel fibers.
  • Improves residual strength of concrete.
  • Improves impact, shatter, ductility and abrasion resistance of concrete.
  • Enhances durability and toughness of concrete.
  • Pumpable reinforcement
  • Safer and easier to use than wire mesh and rebar
  • Reduction in construction time, since it does not need to be place, cut and chaired.
  • Does not corrode and is highly alkali resistant.
  • Does not absorb water or chemically affect the curing process.
  • Reducing embodied carbon through the replacement of convention steel reinforcement with synthetic structural fibers.

Usage

Sika® Fibermesh®-650 can be successfully used as a safe and simple alternative to wire mesh and rebar. Due to its mechanical properties Sika® Fibermesh®-650 is recommended for use in following applications:
  • Industrial and warehouse slab on grade
  • Residential and commercial slab on grade
  • Toppings and overlays
  • Replacement for wire mesh or rebar
  • Composite metal decks
  • Precast reinforcement - septic tanks and burial vaults
  • Exterior pavements and parking areas

Application

Application Information

Mixing

Sika® Fibermesh®-650 in a dispersible bag can be added directly to the concrete mixing system after the batching of the ingredients and mixed for 4 to 5 minutes or 70 revolutions.  The addition of Sika® Fibermesh®-650 at the recommended dosage rates may decrease the slump; however, additional water should not be added. Only a water reducing or high range water reducing admixture should be used to adjust concrete to the desired workability.

Application

The addition of Sika® Fibermesh®-650 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®-650 can be used in power/hand troweled concrete, colored and broom finished concrete. Fiber reinforced concrete can be finished by most finishing techniques as indicated in ACI-302. Proper timing and workmanship are important when using a macro synthetic fiber to insure fiber is not elevated at the surface. 

 
Consumption

Recommended Dosage

The dosage of the Sika® Fibermesh®-650 will vary according to the type of application and the performance requirements of the project.  Standard recommended dosage rate of Sika® Fibermesh®-650 is between 1.8–4.45 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.
