SikaFiber® Novomesh®-950

Blended Fiber - Macro Synthetic and Micro Synthetic

SikaFiber® Novomesh®-950 is an engineered blend of macro and micro synthetic reinforcing fibers specifically designed for the reinforcement of concrete. SikaFiber® Novomesh®-950 is 100% virgin copolymer polypropylene macro and micro fibers deisgned to provide the optimum combination of plastic shrinkage and long term reinforcement within the concrete.  Specifically engineered and manufactured in an ISO 9001 certified manufacturing facility. SikaFiber® Novomesh®-950 previously Novomesh 950 or SikaFiber Force 950.

  • Macro-synthetic/micro-synthetic fiber blend for secondary reinforcement
  • Inhibits formation of plastic shrinkage and plastic settlement cracks
  • Provides impact, abrasion and shatter resistance
  • Provides higher levels of residual strength
  • Provides improved durability and reduces permeability
  • Control of drying shrinkage and temperature cracking
  • Good finishing characteristics
  • Three dimensional reinforcement in concrete
  • Safer, quicker and easier to use than traditional reinforcement
  • Packaged for easy dosing into the concrete mix
  • Reducing embodied carbon through the replacement of convention steel reinforcement with synthetic structural fibers.

    Application

    Application Information

    Mixing

    SikaFiber® Novomesh®-950 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 SikaFiber® Novomesh®-950 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 SikaFiber® Novomesh®-950 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®-950 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 SikaFiber® Novomesh®-950 will vary according to the type of application and the performance requirements of the project.  Standard recommended dosage rate of SikaFiber® Novomesh®-950 is between 5–10 lbs/cu. yd. (3–6 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
