SikaFiber® Novocon® HE-4550

Steel Fiber - Type I

SikaFiber® Novocon® HE-4550 steel fibers are designed specifically for the reinforcement of concrete. SikaFiber® Novocon® HE-4550 is a cold drawn hooked end (HE) steel fiber, to provide optimum anchorage within the concrete. SikaFiber® Novocon® HE-4550 steel fibers are specifically designed to meet or exceed the defined performance requirements.  Previously SikaFiber Force 1050 and Novocon HE1050.

  • 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
  • High tensile strength fiber bridging joints and cracks to provide tighter aggregate interlock resulting in increased load-carrying capacity
  • Provides increased ultimate load-bearing capacity which allows possible reduction of concrete section
  • Requires less labor to incorporate into concrete than conventional reinforcement
  • Offers economical concrete reinforcement solutions with greater project scheduling accuracy
  • Ideally suited for hand or vibratory screeds, laser screeds and all conventional finishing equipment

Application

Application Information

Mixing

SikaFiber® Novocon® HE-4550 can be ribbon feed 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® Novocon® HE-4550 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® Novocon® HE-4550 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® Novocon® HE-4550 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® Novocon® HE-4550 will vary according to the type of application and the performance requirements of the project.  Standard recommended dosage rate of SikaFiber® Novocon® HE-4550 is between 25 - 67 lbs/cu. yd. (15–40 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.
