Abstract In this report carbon fibre in the form of braided rope was considered for the possibility of use in reinforcing concrete. Braided carbon fibre ropes were considered for applications such as tendons for prestressed concrete or grids for slabs and beams. Experimental investigations that were carried out by Cortis, Kaczmarcyzyk, & Pearce, (2013) reported a low bonding strength between concrete and braided carbon fibre rope. This means braided carbon fibre despite having exceptional mechanical properties may not be used for prestressed concrete. However, braided carbon fibre may be used for post-tensioning of concrete.

Grid reinforcement may be the only way to effectively to use carbon fibre for concrete reinforcement. Application of grid reinforcement in concrete was reported to increase the pull out load (Seo & Djamaluddin, 2006). This could be due to large surface area of the grid that is exposed to concrete bonding in comparison with adhesive bonding on ropes. Therefore, grid carbon fibre reinforcement may be used to reinforce concrete slabs, wall panels and beams.
