SFB 532:  Textile-Reinforced Concrete - Development of a New Technology

• Subject Area: Construction Engineering and Architecture ; Mechanical and Industrial Engineering
• Term: from 1999 to 2011
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 5483592

Cement based concrete, the main structural material for buildings, offers a large field of possibilities in design and production technologies. Concrete is the most economical building material to carry compressive loads. Because of its low tensile strength a steel reinforcement is normally necessary. The collaborative research centre 532 investigates the bases on the application of the new composite material "Textile-Reinforced Concrete", in which the steel reinforcement is replaced by a textile reinforcement made of glass-, carbon- or plastic fibres. Compared to steel the textiles offer some advantages such as the corrosion resistance and the placing close to the concrete surface. Therefore the new composite material makes it possible to produce and use very thin-walled, highly stressed concrete elements with good mechanical characteristics, manufactured in an industrial way. The primary targets of the collaborative research centre 532 are the study and development of the mechanical characteristics of the materials, the production technologies, the mechanical modelling of the load-bearing behaviour of the composite material, the jointing methods and the development of an industrial production of 3D-structures, their economic and environmental evaluation and the search of possible areas of application. The knowledge of the new composite material "Textile reinforced
concrete" will allow to open new and innovative fields of applications in the building industry as well as in related areas, to extend the market for technical textiles and concrete products. The research centre consists of sixteen subprojects, in which scientists cooperate interdiciplinarily in the fields of concrete and textile materials, architecture, civil, chemical and production engineering.
