Abstract: Textile reinforced concrete has been developed in the last 20 years to a modern and quite broadly applicable composite material. One of the major issues of new materials is the technique to produce building members in a professional manner. Therefore different production technologies have been developed in the past, e. g. normal casting, laminating technique, spraying and laminating, spinning, and, as a good example for a continuous process, the extrusion. There are different issues which have to be solved if one wants to extrude members of textile reinforced concrete. Firstly the fresh concrete properties must meet this process. This includes special mixing processes and mix compositions. The flow of concrete has to be studied depending on the geometry of the cross-section of the member. And last but not least a system has to be implemented which allows the guidance of the textile into the flow of concrete without disturbing the inner structure and damaging the structure of the textile. In this paper the development of mixture design, mixing procedure and the mouth of the extrusion machine will be described and some experimental results in tensile tests are shown.
