Sika® CarboDur® E

Pultruded carbon fibre plates for structural strengthening as part of a Sika CarboDur® system

Sika® CarboDur® E plates are pultruded carbon fibre reinforced polymer (CFRP) laminates, designed for strengthening concrete, timber, masonry, steel and fibre reinforced polymer structures.
Sika® CarboDur® E plates are bonded onto the structure as externally bonded reinforcement using Sikadur®-30 epoxy resin based adhesive.Refer to the relevant Product Data Sheet for more detailed adhesive information.

  • Non corroding
  • Very high strength
  • Excellent durability
  • Unlimited lengths, no joints required
  • Low system thickness, simple execution of plate intersections or crossings
  • Easy transportation (rolls)
  • Lightweight, very easy to install, especially overhead (without temporary support)
  • Minimum preparation of plate, applicable in several layers
  • Smooth edges without exposed fibres as result of production by pultrusion
  • Testing and Approvals available

Usage

Sika® CarboDur® E 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® E 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 the 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® E externally bonded to other substrates
For application of CarboDur® plates to all other substrates (brick, stone, steel, wood, fibre reinforced polymer etc.)  refer to the Technical Information Manual or contact Sika technical service for detailed advice.

SUBSTRATE PREPARATION

Concrete must be cleaned and prepared to achieve a laitance and contaminant free, open textured surface.
Refer to the Technical Information Manual for further information.
