Principles for the Extrusion of Carbon Reinforced Concrete Structures
The aim of subproject D02 is the investigation of a material-saving and economic production process for thin, reinforced structures with variable concrete cross sections, which are characterized by simple to strongly curved and complex geometries. Therefore the continuous production with an extruder and a subsequent forming of these structures is focused. Extrusion has the technological and economic potential to produce complex components with high precision and quality without time-consuming and cost-intensive formwork and reinforcement processes.
Not only does rapid production significantly increase cost-effectiveness, it also counteracts the scarcity of raw materials through waste minimization and material-saving component geometries. The integration of technical textiles made of carbon in the extrusion process further increases the load-bearing capacity of the component.
