Abstract:
Within the framework of an AiF research project, production methods for the serial batch production of building elements made of textile reinforced concrete were examined. The research work comprised the manufacturing techniques of laminating, casting, spraying and spinning as well as combinations of these methods. In the beginning the main focus was directed on the production and manufacturing technique with the adjustment of fine grained concrete and fabrics to the respective production technique and the development of spacers. Afterwards building elements were manufactured applying selected production techniques to be able to examine the entire manufacturing process of the building elements. The entire manufacturing process included the choice of the suitable production technique, the design of the building elements, the pre-confectioning of the fabrics, the production of the building elements as well as their testing and the discussion of the results. This paper presents the results of the research work. At first the production methods are explained. Afterwards the entire manufacturing process is exemplarily described for the production of spun concrete tubes as well as for elements of an integrated formwork.
