The Collaborative Research Centre (CRC, in German: SFB) 528 was set up of the DFG at the TU Dresden on July 1, 1999. The following pages summarise the contents and aims of the CRC 528 and illustrate the interdisciplinary networking between all involved research institutions of the research areas engineering, civil engineering, surveying and material sciences. The DFG’s funding of the basic research ended in June 2011. But the research on the addressed topic textile reinforced concrete (TRC) – with a new focus on research transfer into practice – lasts until now. Cooperating partners are the Deutsche Zentrum Textilbeton (German Centre Textile Reinforced Concrete) and the TUDALIT e.V. (registered association TUDALIT).
Research Programme
Technical fibres with excellent mechanical properties, like alkali-resistant glass or carbon, can be used for the manufacturing of textile reinforcement grids that can be arranged in cementitious matrices according the force flow. The result is the new and innovstive composite material textile reinforced concrete (TRC). it can be used for both the production of new concrete components and for strengthening and repair of existing buildings. Compared to steel, these high strength fibre materials have no risk of corrosion. So it is possible to build very thin TRC components, and even thin TRC layers are sufficient to increase the load bearing capacity in case of strengthening.
On wooden constructions, textile laxers are able to compensate the differences in resistance and stiffness caused by anisotropy and increase durability at the same time. Frthermore, a high increase of sustainability and durability of connections can be achieved using textile structures.
Theoretical and experimental investigations in the five project areas of CRC 528 "Textile Reinforcements for Strengthening and Repair" will create the basic knowledge regarding the materials, mathematical description, constructive design and calculation, application techniques, practical implementation and long-term properties and thus safety and durability.
