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以及使用矿化空心体来高效生产多功能建筑构件。根据研究项目-Optimalstrukturen aus functional gradierten Betonbauteilen-的结果，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上游流动混合器使用两个喷嘴来扩大材料应用。为了生产性能范围更广的混凝土，需要开发矿化空心体及其在工艺中的集成。最终目标是生产复杂的结构部件，以创建分段结构。工艺链的自动化是多功能级配混凝土建筑构件可重复生产的关键方面。对于工艺参数的动态适应，从设计、通过CAD模型计算最佳密度分布和要求依赖的混凝土混合物到材料应用和骨料的诱导的整个过程，如矿化中空体或纤维，必须集成到过程控制中。在前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。研究的重点是一方面系统地控制材料应用，分别用于生产三维建筑构件的喷射流;另一方面，基于模型的矿化空心体和其他骨料的控制诱导，以形成扩展性能范围的功能分级。此外，在本研究中，可回收性和节能是另一个主要主题。

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.
