On decay follows full regeneration. Such circularity is not yet rooted in the principles of structural engineering. At the end of service, buildings are demolished and, when feasible, disassembled for recycling. This also applies to reinforced concrete construction with its vast building stock. Demolition triggers a fatal downcycling process in which the concrete is used as bulk material or disposed of in a landfill. However, near the end of service, capacity deficits are seldom the key factor; utilization limits or construction regulations are decisive instead. The consequences are an enormous waste of resources, such as sand or gravel, greenhouse gas emissions from reprocessing and waste. Reuse means the repeated use of reinforced concrete as structural components (modules). No longer needed buildings are deconstructed into load-bearing elements, characterized, refurbished, and assembled into new modular structures, creating a circular modular system. The Collaborative Research Center 1683 at Ruhr University Bochum is a multidisciplinary cooperation addressing modular reuse. It develops design and repair concepts for load-bearing structures made of reused reinforced concrete, automated characterization and processing, and processes for logistics, deconstruction, and sustainability assessment.

However, on-site reuse offers ecological and economic benefits. A prerequisite for this is a detailed characterization of the existing foundations in terms of their structural integrity, potential damage, and remaining load-bearing capacity. Limitations arise, particularly due to the immutable reinforcement arrangement, which restricts the load-bearing capacity for new structures. Strengthening or supplementing the existing foundations may be necessary, which is often associated with high greenhouse gas emissions. Bio-cementation through bacterial calcium carbonate precipitation offers a sustainable alternative, but its mechanical properties and bonding effect with existing foundations still need to be investigated. The use of wastewater for bio-cementation through ureolysis, as well as the alternative path of denitrification, are promising with regard to cost reduction and efficiency improvement, but have so far been largely unexplored. This paper describes two sub-projects of the SFB 1683: B04, which deals with the characterization of foundations using inverse identification methods, and A04, which investigates bio-based adaptations of existing foundations for sustainable reuse.</p>","PeriodicalId":55396,"journal":{"name":"Bautechnik","volume":"102 8","pages":"471-482"},"PeriodicalIF":0.5,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144905670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three educational escape rooms developed independently by the authors in the field of geotechnics are presented. In each case, the participating students have the goal of freeing themselves from a geotechnical laboratory. Solution paths and examples of escape room puzzles are presented and provide inspiration for transferring them to other areas of civil engineering, such as laboratory exercises.

Reusing existing reinforced concrete elements from existing structures offers a sustainable way to reduce greenhouse gas emission and resource consumption. This requires the processing of deconstructed, aged reinforced concrete elements with individual properties and edges that enable further use and integration into new modular load-bearing structures. The focus is on automating the individual subprocesses to achieve a standardized and quality-assured process. This contribution presents a comprehensive concept for the automated fine processing of reused concrete elements. First, requirements for the fine processing are defined, from which a process engineering approach for the preparation of the concrete elements can be derived. Target parameters for the reused modules after fine processing are derived from experimental investigations. Cutting tests with variable processes and boundary conditions and associated load tests show that concrete sawing allows the precise manufacturing of flat surfaces. By contrast, water jet cutting reduces the accuracy and thus the load-bearing capacity as pressure contact. These and future results will be successively integrated into the simulation-based testing of processing methods and planning of tool-specific paths of the automated fine processing. Moreover, extension with a system-specific data model enables a linked and individualised energy analysis and forecasting of the overall system.</p>","PeriodicalId":55396,"journal":{"name":"Bautechnik","volume":"102 8","pages":"436-448"},"PeriodicalIF":0.5,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144905639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
