The goal of this research is the efficient production of multifunctional building elements by optimizing the automated process and also through the use of mineralized hollow bodies. According to findings from the research project -Optimalstrukturen aus funktional gradierten Betonbauteilen- automated weighing, dosing and mixing technology is needed to get an optimum process flow. For the increase of efficiency and energy saving, the material application should also be expanded by using two spray nozzles through one spray nozzle and an upstream flow mixer. In order to produce concrete in the extended range of properties, the development of mineralized hollow bodies and their integration in the process is needed. The ultimate goal is the production of complex structured components for creating segmented structure.The automation of the process chain is a key aspect for the reproducible production of multifunctional graded concrete building elements. For the dynamic adaptation of the process parameters, the whole process from design, calculation of the optimal density distribution over the adoption of the CAD-models and the requirement dependent mixture of concrete to material application and the induction of aggregates, as mineralized hollow bodies or fibers, has to be integrated into a process control. The development of modeling and control of the dynamic process started in the previous project needs to be continued. Focus in the research is on the one hand the systematic manipulation of the material application respectively of the spray jets for producing three-dimensional building elements; on the other hand, the model-based controlled induction of mineralized hollow bodies and other aggregates to form functional grading in an extended properties range.Furthermore, in this research the recyclability and energy saving is another main topic.
