SikaFiber® Novomesh® CAL-51

Blended Fiber - Macro Synthetic and Micro Synthetic

SikaFiber® Novomesh® CAL-51 is an engineered blend of macro and micro synthetic reinforcing fibers specifically designed for the reinforcement of concrete. SikaFiber® Novomesh® CAL-51 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® CAL-51 previously Novomesh CAL-51.

  • Macro-synthetic/micro-synthetic fiber blend for secondary reinforcement
  • Inhibits formation of plastic shrinkage and plastic settlement cracks
  • Control of drying shrinkage and temperature cracking
  • Provides impact, abrasion and shatter resistance
  • Provides higher levels of residual strength
  • Provides improved durability
  • Reduces permeability
  • Good finishing characteristics
  • Pumpable reinforcement
  • Reducing embodied carbon through the replacement of convention steel reinforcement with synthetic structural fibers.

Application

Application Information

Mixing

SikaFiber® Novomesh® CAL-51 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® CAL-51 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® CAL-51 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® CAL-51 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® CAL-51 will vary according to the type of application and the performance requirements of the project.  Standard recommended dosage rate of SikaFiber® Novomesh® CAL-51 with the 3 to 1 macro to micro blend is 4 lbs/cu. yd. (2.4 kg/m3) of concrete. Standard recommended dosage rate of SikaFiber® Novomesh® CAL-51 with the 4 to 1 macro to micro blend is 5 lbs/cu. yd. (3 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.
