Concrete plays a leading role among construction materials. It is characterized by its enormous adaptability to changing requirements. For a long time, further development primarily concerned technical progress in building construction. In recent decades, it has increasingly been applied to the entire life cycle as well as to material-related aspects of environmental and climate protection, with a particular focus on resource efficiency and the avoidance of climate-damaging emissions. The current development is accompanied by increasing complexity in terms of starting materials, formulations and the manufacturing process.

The aim of the project is to establish an end-to-end digital process for describing the material behaviour of concrete throughout the entire production process. By making these concepts available, a simple exchange of data, models and workflows in accordance with the FAIR Data principles is to be made possible, on the basis of which the enormous potential of this material for improving production processes and for resource-saving material use can be opened up for a wide range of users.

In cooperation with the MaterialDigital platform, an ontology and simulation workflows based on it are developed. Based on a graph database and a probabilistic linking of simulation and experiment integrated into the workflows, the innovation potential of the methodology is finally presented as an example for the optimization of a special precast part made of high-performance concrete.

LeBeDigital - Lifecycle of Concrete - Ontology Development for the Process Chain of Concrete Production

The joint project LeBeDigital sets itself the task of developing a generally available data and knowledge management system tailored to the process of concrete production on the basis of generally applicable ontologies and workflows. With the development of this knowledge-based database, experience and research data at a high level and with deep information content are to be made permanently usable and publicly accessible for the general public. In the project, the Federal Institute for Materials Research and Testing is working on the topics of ontologies and workflows for processes, models and mapping in databases.

Topics of BAM

Conceptual design, implementation and validation of process-related ontologies and workflows
Division Building Materials

Development of modeling workflows in a multiscale context, implementation of these workflows within the platform MaterialDigital as well as development and implementation of the specific ontologies for the simulation models
