Efficient automated production of multifunctional and graded building elements with mineralized hollow bodies

这项研究的目标是通过优化自动化过程和使用矿化的中空体来高效地生产多功能建筑元素。根据研究项目--Optimalstrukturen Aus Funktional Gradierten Betonbauteilen的研究结果，需要自动称重、配料和混合技术来获得最佳工艺流程。为了提高效率和节能，还应通过一个喷嘴和一个上游混合器，使用两个喷嘴，以扩大材料的应用范围。为了生产具有更大性能范围的混凝土，需要开发矿化中空体并将其整合在过程中。最终目标是生产复杂的结构构件，以创建分段结构。过程链的自动化是可重复生产多功能级配混凝土建筑构件的关键方面。为了实现工艺参数的动态调整，必须将从设计、计算采用CAD模型的最优密度分布、混凝土的需求依赖混合料到材料应用以及骨料作为矿化空心体或纤维的诱导的整个过程集成到一个过程控制中。上一个项目中开始的动态过程建模和控制的发展需要继续下去。研究的重点一方面是对分别用于生产三维建筑元素的喷射器的材料应用进行系统的操纵；另一方面，基于模型的控制诱导矿化空心体和其他集料在扩展的性能范围内形成功能级配。此外，可回收性和节能是本研究的另一个主要课题。

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.
