New regulations, carbon concrete, cement-free concretes, and artificial intelligence are the focus of the 33rd Technical Symposium of the Landesgütegemeinschaft Instandsetzung von Betonbauwerken NRW e. V. (LIB NRW). Under the theme “Concrete Maintenance—Today for the Future,” the event will take place on February 2, 2027, in Dortmund.
The symposium will address current technical, legal, and digital developments in concrete repair and relate them to real-world examples. Dipl.-Ing. Arne Goslar of Kempen Krause Ingenieure GmbH will open the event with an overview of recent additions, amendments, and clarifications to the regulations governing concrete repair, as well as the ongoing work of the relevant federal working committees.
Carbon concrete and cement-free concretes
Dr.-Ing. Marcus Hinzen of Solidian GmbH will focus on the rehabilitation and reinforcement of underground parking garages, multi-story parking structures, and industrial areas using carbon concrete. He will present commercially available non-metallic carbon reinforcements as well as special spacers for their installation. Using application examples, Hinzen will highlight the possibilities offered by high tensile strength, corrosion resistance, and chloride resistance. Approaches for low-crack surfaces and surface protection systems will also be discussed.
Dr.-Ing. Carola Edvardsen, Cowi A/S, will present research findings and initial applications of cement-free concrete, in which Portland cement is replaced by industrial byproducts. The focus will be on the potential for CO₂ reduction as well as possible applications in new construction and concrete repair.
Legal Issues and AI in the Construction Industry
Dr. Stelzner from the law firm Kapellmann & Partner will address the acceptance of concrete repair sites in connection with the third-party monitoring report. His presentation will cover the interfaces between acceptance, third-party monitoring, and the third-party monitoring report, as well as the resulting implications under contract law and building codes.
After the lunch break, Lukas Hartmann from Helden im Handwerk will use concrete examples to demonstrate where artificial intelligence can already be applied in construction companies, engineering firms, and administrative offices, and what requirements, limitations, and responsibilities must be taken into account.
The event will conclude with the keynote address “The Future Begins in the Mind” by Ursula Helml. Accompanying the presentations, a trade exhibition will provide an opportunity for professional exchange and information on current products and solutions.
The 33rd Technical Symposium will take place on February 2, 2027, at the Westfalenhallen Congress Center in Dortmund. The trade exhibition opens at 8:00 a.m. The early-bird discount is valid through November 15, 2026. The event is recognized as continuing education by the North Rhine-Westphalia Chamber of Civil Engineers.
