Pan-European Historical Material Libraries for Concrete & Rebar (NL, DE, SE, FI, & Eurocodes)

Repository Description: This repository contains two machine-readable material libraries—one for concrete and one for reinforcing steel—covering historical twentieth-century (pre-Eurocode) and modern classifications across the Netherlands, Germany, Sweden, and Finland, and the current Eurocode provision (2000 – present). The libraries are designed to streamline data entry and analysis within a relational database network for storing reusable precast concrete elements reclaimed through deconstruction. Scope and Coverage: Countries: Netherlands, Germany, Sweden, and Finland; plus Eurocode classes. Period: 1916 to present, spanning twentieth-century national standards to EN 206 (concrete) and EN 10080/EN 10138 (steel). Classifications: Includes historical systems (e.g., K, B, St, W/Wb) and modern classes (e.g., C8/10 – C90/150, B500A/B/C, Y1030 – 2060). Project and Documentation: These libraries were compiled as part of the EU-funded ReCreate project. The ReCreate project researches the process of reusing precast concrete elements through real-life deconstruction and reuse pilots in Europe. The project aims to assess and improve the technical feasibility of a circular life cycle for structural precast elements across the entire value chain from disassembly, quality control, design for reuse and reconstruction. A scientific journal article applying these libraries in a relational database capturing the full value chain of reusable precast concrete elements is currently under review and will be linked here upon publication. Contents: Each spreadsheet library contains: Characteristic mechanical properties where available (e.g., compressive properties, tensile properties, Young’s moduli, strain/ductility notes), organised by country and chronologically. Standard metadata (standard name, edition/year, notes/annotations) and bibliographic sources for traceability, wherever available. Versioning rules: If identical classifications recur and are unchanged across multiple standards, their metadata are concatenated into a single record to preserve uniqueness for the relational database. If numeric properties differ, the class/grade is suffixed by the distinguishing feature (e.g., W28_8.0, W28_9.5). Sources and Completeness: Values for the Netherlands and Germany draw on established historical compendia. Meanwhile, Swedish and Finnish values are compiled from more fragmented archival reviews and theses, where original standards and detailed timelines were difficult to obtain. Hence, these libraries are incomplete, particularly for tensile properties, Young’s moduli, and strain capacities, and will benefit from future verification against original hard-copy standards. All entries include their bibliographic references. This repository may be updated periodically as new information becomes available. Notes: Please cite the dataset DOI when using these libraries. Contributions, errata, and knowledge on the topics are always welcome.
