The Collaborative Research Centre (SFB) 1683 deals with the question of how concrete construction can become more environmentally friendly and sustainable. Instead of demolishing and recycling concrete structures, we reuse components such as walls, slabs or rods. These components are removed by sawing or water jetting, tested, processed and then reassembled like building blocks.
More than 50 scientists from Ruhr University Bochum, the Federal Institute for Materials Research and Testing, the Karlsruhe Institute of Technology (KIT) and the University of Stuttgart are working together on these concepts. We show how reused components become new load-bearing structures, how dismantling and non-destructive component testing work and how the individual steps are controlled. Automated processes make reprocessing faster and more efficient.

Sub-project C03 focuses on the dismantling of existing in-situ concrete source structures into reusable elements. The first step is to evaluate a large number of requirements for dismantling. This results in a data model with geo-metric and semantic information. For the geometric segmentation into reusable elements, efficient decomposition algorithms will be developed. In addition, spatio-temporal constraints for dismantling sequences of concrete ele-ments will be identified, taking into account both structural safety and logistical aspects. A key outcome will be the development of a construction kit containing the identified concrete elements with high recycling potential.

Sub-project INF is concerned with the research data management of the CRC. The consistent storage, sharing and processing of data promotes and structures collaboration. Metadata schemas and ontologies will be used to for-mally describe and link data sets. Data will be made available for re-use according to the FAIR principles. A central knowledge management system will be established and continuously maintained. A crowdsourcing approach for building data will be implemented and data will be collected for the CRC demonstrators. A training and qualifi-cation programme in research data management will be developed and offered to the members of the CRC.

Subproject C4 develops simulation models for the numerical analysis of the excavation of the ground and the transport of the excavated material in Earth Pressure Balance shield machines driving through strongly variable ground conditions. The models provide an in-depth understanding of the fracture and fragmentation processes in the ground, the loadings acting on the excavation tools, and the transport and mixture processes and the pressure distribution in the excavation chamber. The dependencies on the geological conditions, the machine design and the soil conditioning are explored to identify potentials for improvements of the cutting wheel design and the machine technology.
