SikaFiber® Novomesh®-850

Blended Fiber - Steel Fiber Type V and Micro Synthetic

SikaFiber® Novomesh®-850 an engineered blend of steel and micro fibers are designed specifically for the reinforcement of concrete. SikaFiber® Novomesh®-850 is a cold drawn continuously deformed steel fiber and 100 percent virgin homopolymer polypropylene graded multifilament micro synthetic fiber. The blend of steel and micro fiber provide optimum combination of plastic shrinkage and long term reinforcement within the concrete. SikaFiber® Novomesh®-850 previously Novomesh 850 or SikaFiber Force 850.

  • Provides uniform multi-directional concrete reinforcement
  • Increases crack resistance, ductility, energy absorption or toughness of concrete
  • Improves impact resistance, fatigue endurance and shear strength of concrete
  • Steel fiber bridging joints and cracks to provide tighter aggregate interlock resulting in increased load-carrying capacity
  • Provides increased ultimate load-bearing capacity 
  • Requires less labor to incorporate into concrete than conventional reinforcement
  • Micro synthetic fiber reduces plastic shrinkage cracking

Application

Application Information

Mixing

SikaFiber® Novomesh®-850 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. Only a water reducing or high range water reducing admixture should be used to adjust concrete to the desired workability.

Application

The addition of SikaFiber® Novomesh®-850 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

SikaFiber® Novomesh®-850 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 importante when using a steel fiber to insure the fiber is not elevated at the surface.
Consumption

Recommended Dosage

The dosage of the SikaFiber® Novomesh®-850 will vary according to the type of application and the performance requirements of the project.  Standard recommended dosage rate of SikaFiber® Novomesh®-850 is between 24 - 48 lbs/cu. yd. (14–28.5 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.
