Multi-axial warp knits for subsequent reinforcement of concrete masts
Textile reinforced concrete is not only suited for the production of new parts but can also be used on existing structures for maintenance, restoration, reinforcement, and increase of the load bearing capacity. This is exemplarily shown by subsequent reinforcement of existing concrete masts. After a service time of several decades a large number of steel and steel reinforced concrete masts show damages which are evaluated as repairable. Longitudinal cracks are non-critical whereas torsional damages of the mast ends require advanced methods of restoration. In contrast to known methods of conservation or restoration, respectively, the solution developed at Dresden University of Technology from the outset aims at the increase of the load bearing capacity of the masts. This is achieved by the application of a textile reinforced concrete layer over the entire mast length. The method as well as the results gained are introduced in the paper. Main focus is on the requirements regarding the design of the textile reinforcement structure and its manufacture, the compound behavior of reinforcement and basic concrete, and on load bearing tests of reinforced mast segments.
