Sika® CarboDur® S

PULTRUDED CARBON FIBRE PLATES FOR STRUCTURAL STRENGTHENING AS PART OF THE SIKA® CARBODUR® SYSTEM

Sika® CarboDur® plates are pultruded carbon fibre reinforced polymer (CFRP) laminates, designed for strengthening concrete, timber, masonry, steel and fibre reinforced polymer structures.
Sika® CarboDur® plates are bonded onto the structure as externally bonded reinforcement using Sikadur®-30 epoxy resin based adhesive for normal, or Sikadur®-30 LP epoxy resin based adhesive for elevated temperatures during application and / or service.
Please refer to the relevant Product Data Sheet for more detailed information about each of these adhesives. Suitable for use in hot and tropical climatc conditions.

  • Non-corroding
  • Very high strength
  • Excellent durability and fatigue resistance

Usage

Sika® CarboDur® systems are used to improve, increase or repair the performance and resistance of structures for:
Increased Load Carrying Capacity:
  • Increasing the load capacity of floor slabs, beams and bridge sections
  • For the installation of heavier machinery
  • To stabilise vibrating structures
  • For changes in building use
Damage to structural elements due to:
  • Deterioration of the original construction materials
  • Steel reinforcement corrosion
  • Accidents (Vehicle impact, earthquakes, fire)
Improvement of serviceability and durability:
  • Reduced deflection and crack width
  • Stress reduction in the steel reinforcement
  • Improved fatigue resistance
Change of the structural system:
  • Removal of walls and / or columns
  • Removal of floor and wall sections to create access / openings
Resistance to possible events:
  • Increased resistance to earthquakes, impact or explosion etc.
To repair design or construction defects such as:
  • Insufficient / inadequate reinforcement
  • Insufficient / inadequate structural depth

Application steps

SUBSTRATE QUALITY

Sika® CarboDur® plates externally bonded to the concrete surface
Recommended minimum concrete pull-off strength after surface preparation:

  • Mean: 2.0 N/mm2
  • Minimum: 1.5 N/mm2

The effective concrete pull-off strength after surface preparation has to be verified.
If concrete pull-off strength is below the stated minimum requirements, alternative Sika solutions are available:

  • CarboDur® applied in slots as near surface mounted (NSM) reinforcement
  • SikaWrap® fabrics: Please refer to the Product Data Sheet for the SikaWrap® fabrics

Concrete must generally be older than 28 days (dependent on curing conditions and the type of concrete etc.)

 
Sika® CarboDur® externally bonded to other substrates
For application of CarboDur® plates to all other substrates (brick, stone, steel, wood, fibre reinforced polymer etc.) please refer to the “Method Statement for Sika® CarboDur® Externally Bonded Reinforcement”. Contact Sika Technical Department for detailed advice.

SUBSTRATE PREPARATION

Concrete must be cleaned and prepared to achieve a laitance and contaminant free, open textured surface.
Please also refer to the “Method Statement Sika® CarboDur® Externally Bonded Reinforcement”.
