SikaFiber® Novocon® HE-7535 (GB)

Steel fibres for concrete

SikaFiber® Novocon® HE-7535 (GB) steel fibres are designed specifically for the reinforcement of concrete, mortars and other cementitious mixes. SikaFiber® Novocon® HE-7535 (GB) is a cold drawn wire fibre, deformed with hooked ends to provide optimum performance within the concrete mix. SikaFiber® Novocon® HE-7535 (GB) steel fibres are European Standard - EN 14889-1:2006 compliant and have been specifically designed to meet or exceed the defined performance requirements.

  • 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 fibre bridgies joints and cracks to provide increased load-carrying capacity
  • Increased ultimate load-bearing capacity allows 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
  • Requires no minimum amount of concrete cover
  • Always positioned in compliance with codes
  • Safe and easier to use than traditional reinforcement
  • Reduces construction time
  • Leads to uniform application of shotcrete thickness

Application

Application Information

Compatibility

SikaFiber® Novocon® HE-7535 (GB) 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
SikaFiber® Novocon® HE-7535 (GB) steel fibres can be added during or after the batching of the concrete but should never be added as the first component. Such devices as conveyor belts, chutes and dispensers may be used to add fibres to the mixer at the ready mix plant. After the fibres have been added, the concrete should be mixed for sufficient time (minimum 5 minutes at full mixing speed) to ensure uniform distribution of the fibres throughout the concrete. The use of mid or high-range water reducing admixtures can be advantageous, but is not essential.
Placing
SikaFiber® Novocon® HE-7535 (GB) steel fibres can be pumped and placed using conventional equipment. Hand or vibratory screeds and laser screeds can be used with SikaFiber® Novocon® HE-7535 (GB) steel fibres.
Finishing
Conventional finishing techniques and equipment can be used when finishing SikaFiber® Novocon® HE-7535 (GB) 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 minimise fibre exposure on the surface.
