Why reinforce columns with carbon fiber?
\r\n<\/span><\/span><\/h2><\/header>
<\/div>

Reinforced concrete and metal columns lose their load-bearing capacity over time due to:<\/p>\n

\u2714 Reinforcement corrosion<\/p>\n

\u2714 Cracking<\/p>\n

\u2714 Increased loads<\/p>\n

\u2714 Construction design errors<\/p>\n

External carbon fiber reinforcement<\/strong>\u00a0restores up to\u00a095%<\/strong>\u00a0of the structural strength without altering the geometry or halting operations.<\/p>\n<\/div><\/div><\/div><\/div>

    \n
  1. Horizontal reinforcement<\/strong>\n
      \n
    • Uni- or bi-directional woven tapes\/webs.<\/li>\n
    • Winding pitch is determined by design loads.<\/li>\n<\/ul>\n<\/li>\n
    • Vertical Reinforcement<\/strong>\n
        \n
      • Carbon fiber lamellas supported by rounded corners.<\/li>\n
      • Fiber orientation aligns with the column axis.<\/li>\n<\/ul>\n<\/li>\n
      • Combined Reinforcement<\/strong>\n
          \n
        • Integrates both horizontal and vertical carbon fiber layers.<\/li>\n
        • Optimal for columns subjected to complex loading conditions.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n<\/div>

                \n
              • Removing dust, rust, and deteriorated concrete.<\/li>\n
              • Filling cracks and defective areas with repair mortars (injection for up to 5 mm, standard mortars for larger areas).<\/li>\n
              • Rounding of corners (to mitigate local stress concentrations).<\/li>\n<\/ul>\n<\/li>\n
              • Carbon Fiber Application<\/strong>\n
                  \n
                • Surface priming.<\/li>\n
                • Bonding of tapes\/lamellas with epoxy adhesive, followed by rolling.<\/li>\n
                • Multilayer reinforcement (according to the calculation scheme).<\/li>\n<\/ul>\n<\/li>\n
                • Finishing treatment<\/strong>\n
                    \n
                  • Curing until full polymerization (min. 48 hours).<\/li>\n
                  • Decorative finishing (if specified).<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n
