Betonbauwerke mit besonderen Anforderungen hinsichtlich der Nachhaltigkeit unter Berücksichtigung des BBQ-Konzepts
Maßnahmen zur Reduzierung von Treibhausgasemissionen und Schonung der Ressourcen (Anwendungsfall 0)
Schack, Tobias / Wiens, Udo / Haist, Michael
In dem Beitrag wird auf den Anwendungsfall 0 des neu eingeführten Konzepts der Betonbauqualitätsklassen (BBQ) in DIN 1045-1000, Tabelle 2, eingegangen. Der Anwendungsfall 0 umfasst Anwendungen fur Betonbauwerke mit besonderen Anforderungen an die Nachhaltigkeit und das Bauen im Bestand. Diese Anwendungen sind in der Regel projektspezifisch zu vereinbaren, weshalb in DIN 1045-1000:2023-08 eine Einstufung in BBQ-S vorgenommen wurde. Zur Umsetzung werden u.a. Maßnahmen zur Reduzierung von Treibhausgasemissionen sowie zur Ressourcenschonung durch eine geeignete Wahl der Bauteile, Betone und der Bauverfahren beschrieben, von denen der DAfStb einige in seiner Roadmap „Nachhaltig bauen mit Beton“ zusammengestellt hat. Zu diesen Maßnahmen sind im DAfStb entweder bereits Richtlinien veröffentlicht (wie z.B. die THG-Richtlinie) oder sie befinden sich in der Bearbeitung (z.B. Richtlinie „Ultrahochfester Beton“). Die Komplexität muss entsprechend der projektspezifischen Anforderungen bewertet und entsprechend umgesetzt werden.
Concrete structures with special requirements in terms of sustainability, taking into account the BBQ concept (application case 0)
The contribution deals with application case 0 of the newly introduced concept of concrete quality classes (BBQ ) in DIN 1045-1000, Table 2. Application case 0 covers applications for concrete structures with special requirements in terms of sustainability and building renovation. These applications are usually agreed on a project-specific basis, which is why application case 0 is not included in the standard. Application case 0 covers applications for concrete structures with special requirements for sustainability and building renovation. These applications are usually agreed on a project-specific basis, which is why a classification in BBQ-S was made in DIN 1045- 1000. Measures for implementation include measures to reduce greenhouse gas emissions and conserve resources through the appropriate selection of components, concretes and construction methods, some of which the DAfStb (German Committee for Reinforced Concrete) has compiled in its roadmap „Sustainable construction with concrete“. The DAfStb has either already published guidelines for these measures (such as the GHG guideline) or they are currently being developed (e.g. the „Ultra-high-strength concrete“ guideline). The complexity must therefore be assessed in accordance with the project-specific requirements and implemented accordingly
