SikaWrap® Hex-230 C

Carbon fibre fabric for structural strengthening system

SikaWrap® Hex-230 C is a unidirectional carbon fibre fabric. When used in conjunction with Sikadur®-330 epoxy laminating resin, the system can provide a dry lay-up applied composite strengthening system.

  • Lightweight fabric ideal for confined spaces.
  • Dry lay-up process.
  • Use for shear, confinement or flexural strengthening.
  • Flexible, can be wrapped around complex shapes.
  • High strength.
  • Lightweight.
  • Non-corrosive and alkali resistant.
  • Low aesthetic impact.

Application steps

SUBSTRATE PREPARATION

Prepare the concrete surface by sandblasting or grinding (CSP 3 - 4 as per ICRI). Remove any dust or loose particles by means of an industrial vacuum cleaner. The surface must be clean, free from grease and oil and should be dry with the maximum substrate moisture content of < 4 % by weight.
   

The surface to be bonded must be level, with no irregularities or protrusion > 0.5 mm (20 mil). Larger deviations must be levelled with Sikadur®-30, extended with (mix. ratio 1:1 parts by volume) oven-dried silica sand for thicknesses over 3 mm (1/8 in).
The concrete adhesive strength must be verified following surface preparation by random pull-off testing (ACI 503R) at the engineer’s discretion. Minimum tensile strength, 1.5 MPa (218 psi) with concrete substrate failure. All corners of the structure must be rounded to a radius of 12 mm (1/2 in).
