UAE Dubai Standard high quality Carbon Fiber CFRP Wrap for tower retrofitting
Carbon Fiber Reinforced Polymers for Structural Strengthening. These fabrics are applied onto the surface of existing structural members in buildings, bridges and other structures. The result is an externally bonded CFRP (carbon fiber reinforced polymer) reinforcement system engineered to increase the structural performance
CFRP strengthening of existing structures can involve complex evaluation, design, and detailing processes, requiring a good understanding of the existing structural conditions along with the materials used to repair the structure prior to FRP installation. The suitability of FRP for a strengthening project can be determined by understanding what FRP is and the advantages it offers, but more importantly, its limitations.
The primary benefit of CFRP systems versus traditional retrofit and repair methods is that significant flexural, lateral, axial or shear strength gains can be achieved with an easy-to-apply composite that does not add significant weight or mass to the structure of building, highway, bridge, tunnel.

Preparation works
Surface must be clean and sound. It may be dry or damp, but free of standing water and frost. Remove dust, laitance, grease, curing compounds, impregnations, waxes, foreign particles, disintegrated materials and other bond inhibiting materials from the surface. Existing uneven surfaces must be filled with an appropriate repair mortar. The adhesive strength of the concrete must be verified after surface preparation by random pull-off testing (ASTM D 4541) at the discretion of the engineer. Minimum tensile strength required is 200 psi (1.4 MPa) with concrete substrate failure (typical).
