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®-
3+, 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.

Uses

Sika® CarboDur® BC suitably experienced and trained
specialist contractors.
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

Characteristics / Advantages

• 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 a 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
