Sika® CarboDur® M

Pultruded Carbon Fibre Plates for Structural Strengthening as Part of the Sika® CarboDur® System

Sika® CarboDur® M plates are pultruded carbon fibre reinforced polymer (CFRP) laminates, designed for strengthening concrete, timber, masonry, steel and fibre reinforced polymer structures.

Sika® CarboDur® M 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.

  • Combination of very high strength and high stiffness
  • Non-corroding

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” Ref: 850 41 05. 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.
Please also refer to the “Method Statement Sika® CarboDur® Externally Bonded Reinforcement” Ref: 850 41 05.
