Sika® CarboDur® BC

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

Sika® CarboDur® BC rods are pultruded carbon fibre reinforced polymer (CFRP) laminates with a circular cross section, designed for strengthening concrete, timber and masonry.
Sika® CarboDur® BC rods are bonded into slots as near surface mounted reinforcement using Sika AnchorFix®-3001, Sika AnchorFix®-3030, Sikadur®-330 or Sikadur®-30 epoxy resin based adhesives for normal application temperatures, or Sikadur®-30 LP* epoxy resin based adhesive for elevated temperatures during application. Sikadur®-300 epoxy resin based adhesive is used for horizontal applications.
Sika® CarboDur® BC rods can also be used for anchoring SikaWrap® fabrics where positive attachment to concrete or masonry is required.

  • Non-corroding
  • Very high strength
  • Invisible once installed, no joints required
  • Excellent durability and fatigue resistance
  • Easy transportation
  • Lightweight, very easy to install
  • Smooth edges without exposed fibres as the result of production by pultrusion
  • Can accept traffic on the strengthened surface (rods not exposed)
  • No surface preparation / levelling of uneven substrates required
  • Improved resistance to fire (compared with externally bonded reinforcement)
  • Testing and Approvals available from many countries worldwide

Usage

Sika® CarboDur® BC rods 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
Combination with other strengthening products:
  • Doweling applications
  • Anchoring of SikaWrap® fabrics
