Novocon® XR-1050

Steel fibres for concrete

Novocon® XR-1050, steel fibres are designed specifically for the reinforcement of concrete, mortars and other cementitious mixes. Novocon® XR-1050 is a leading, general-purpose, low-carbon, cold drawn segment, wire fibre that is continuously deformed to provide optimum performance within the concrete mix. Novocon® XR-1050 steel fibres European Standard EN 14889-1:2006 compliant and specifically designed to meet or exceed the performance and economic requirements of our customers.

  • Provides uniform, multi-directional concrete reinforcement
  • Increases crack resistance, ductility, energy absorption and toughness of concrete
  • Improves impact resistance, fatigue endurance and shear strength of concrete
 
  • High tensile-strength fibre bridges joints and cracks, resulting in increased load-carrying capacity and possible reduction of concrete section
  • Requires less labour 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 Information

Compatibility

Novocon® XR-1050 steel fibres are compatible with all curing compounds, superplasticisers, water reducers, hardeners and coatings.
Consumption

Recommended Dosage

The fibre dosage will vary depending on the type of application, concrete mix design and the performance/toughness requirements of each particular project. Typically, steel fibre dosage will be in the range of 20 kg to 40 kg per cubic meter. Sika technical staff can offer advice on dosage requirements once performance requirements have been established by the project designer/engineer.
Application steps

APPLICATION INSTRUCTIONS

Mixing
Novocon® XR-1050 steel fibres can be added during or after the batching of the concrete but should never be added as the first component. The specified dosage per cubic metre should be steadily added to the concrete mixer and mixed for sufficient time (minimum 5 minutes) at full mixing speed to ensure uniform distribution of the fibres throughout the concrete mix. The use of mid or high-range water reducing admixtures can be advantageous, but is not essential. In order to achieve optimum distribution of fibres we recommend the use of our approved conveyor and/or automated dosing systems which are available upon request. Cardboard boxes and non-degradable bags should NOT be added to the concrete.

 

Placing
Novocon® XR-1050 steel fibres can be pumped and placed using conventional equipment. Hand or vibratory screeds and laser screeds can be used with Novocon® XR-1050 steel fibres.

 

Finishing
Conventional finishing techniques and equipment can be used when finishing Novocon® XR-1050 steel fibre concrete. In some cases an extra bull float process is advised and lowering the angle of the power float blades will help to minimize fibre exposure on the surface.
