Extruded thin-walled textile reinforced concrete components with flexible shape
One of the main challenges in concrete construction at present is the reduction of CO2 emissions. To achieve this, both academia and industry are testing innovative methods, developing CO2-reduced materials, and implementing design principles. CO2-reduced materials are being developed and construction principles are being implemented. In addition to the development of new resource-saving construction materials, innovative manufacturing processes such as additive manufacturing are being tested to use the materials only where they are needed. One promising approach is the use of textile reinforced concrete, which uses woven glass, basalt, aramid or carbon fibres that have a much higher tensile strength than conventional structural steel. As a chemically inert material, carbon fibres offer the additional advantage of being insensitive to corrosion and are therefore particularly suitable for the realisation of durable, material-saving high-performance concrete elements. The extrusion process is an innovative method for implementing new construction concepts from carbon reinforced concrete. In this process, solid to viscous materials are transported through an extruder and pressed through a shaping mouthpiece. This enables the efficient production of precise linear components without the need for formwork. Initial approaches to integrating flexibly impregnated textiles in a laboratory extruder were already carried out in 2012 at the Institute of Building Materials Research at RWTH Aachen University (ibac). However, for the implementation of high-performance textile reinforced concrete components with subsequent longitudinal and transversal shaping with a laboratory extruder, scientifc fundamentals and methods are lacking. In this work, the state of the art of textile reinforced concrete, concrete extrusion and form optimised constructions is presented first. It is followed by four papers in which the scientific research and methods developed in the context of this work are presented. Chapter 2 presents the basic ...
