SikaWrap®-231 C
SikaWrap®-231 C
A range of woven or stitched unidirectional carbon fibre fabrics designed for structural strengthening applications as part of the Sika® Strengthening System.
Application
Structural strengthening of reinforced concrete, masonry, brickwork and timber elements or structures, to increase flexural and shear loading capacity for:
- Improved seismic performance of masonry walls;
- Replacing missing steel reinforcement;
- Increasing the strength and ductility of columns;
- Increasing the loading capacity of structural elements;
- Enabling changes in use / alterations and refurbishment;
- Correcting structural design and / or construction defects;
- Increasing resistance to seismic movement;
- Improving service life and durability;
- Structural upgrading to comply with current standards.
Description
A range of woven or stitched unidirectional carbon fibre fabrics designed for structural strengthening applications as part of the Sika® Strengthening System.
Features and benefits:
All fabrics:
- Multifunctional fabric for use in many different strengthening applications.
- Flexible and accommodating to different surface planes and geometry (beams, columns, chimneys, piles, walls, soffits, silos etc.).
- Low density for minimal additional weight.
- Extremely cost effective in comparison to traditional strengthening techniques.
- SikaWrap®-231 C and SikaWrap®-301 C are manufactured with heat-set weft fibres to keep the fabric stable.
- SikaWrap®-301 C is available in different widths for optimum utilization.
Approvals/ standards:
- All products, UK: Concrete Society Technical Report No. 55, Design guidance for strengthening concrete structures using fibre composite material, 2012.
- Other approvals vary by product: consult manufacturer's literature for details.
Cord and glass fibre fabric products are also available; consult manufacturer for details.
