SikaFiber®-820 Stealth TW

Macro synthetic fibre

SikaFiber®-820 Stealth TW is 100 % virgin copolymer twisted and crimped macro synthetic fibre designed to provide a uniform three-di­mensional reinforcement system for durable con­crete with an excellent finish. Specifically engineered and manufactured in a Sika ISO 9001 certified manufacturing facility.

  • Packaged in small twisted bundles, in degradable bags that are easy to use during mixing
  • Engineered self-fibrillating macro fibre creating a high fibre network in the concrete matrix and designed to create an outstanding finish and performance in a hard troweled slab-on-ground (applicable, but not limited to, for designs by ACI 332, ACI 360, and ACI 544)
  • Cost-effective, three-dimensional reinforce­ment that can replace or reduce wire mesh or rebar, and steel fibres
  • Reduced embodied carbon through the re­placement of conventional steel reinforcement with synthetic structural fibres
  • Increased safety on job site; remove lifting of reinforcement, bending, and tripping hazard
  • Reduction in construction time. No cutting, pla­cing, tying, and chairing of the steel is required
  • Pumpable reinforcement with reduced wear on pumps and hoses compared to steel fibres
  • Reduced permeability
  • Increased ductility, flexural toughness and post first crack of concrete
  • Increased durability due to high chemical resistance and corrosion-free
  • Reduction of plastic shrinkage and settlement cracking
  • Improved impact, shatter, and abrasion resistance of the concrete

Mixing

Guidelines for typical use of SikaFiber®-820 Stealth TW

   

Adjust slump prior to batching SikaFiber®-820 Stealth TW. The fibres will affect the apparent slump of the concrete mix. When starting with a slump of 125 to 200 mm the fibres may have the following effects:

  • 1.8 kg/m3 (3 lb/yd3) will produce approx. 25 mm of apparent slump loss
  • 4.2 kg/m3 (7 lb/yd3) will produce approx. 75 mm of apparent slump loss

   

Mixing

  

  • Plant Mixer: Place bags as last item in the mix on aggregate belt or feed into truck. Do not place the bags on top of each other. 
  • Truck Mixer: Add bags as the last item in the mix. Add one (1) unopened degradable bag at a time. Not more than one (1) bag should be between 2 fins in the truck mixer. Mixing time with the added fibres is five (5) minutes at 15 rpm.
Consumption

Recommended Dosage

The standard recommended dosage rate of SikaFiber®-820 Stealth TW is between 1.8–4.45 kg/m3 (3–7.5 lb/yd3) of concrete.

   

Notes: Dosages outside the recommended dosage range can be used to meet project specific re­quirements. If this is the case, contact your Sika Canada Technical Representative for technical support. The dosage of the SikaFiber®-820 Stealth TW may vary according to the type of application and the performance requirements of the project.
