Database of the RILEM TC 304-ADC interlaboratory study on mechanical properties of 3D printed concrete (ILS-mech)

<p>The RILEM TC 304-ADC has set up a large interlaboratory study on the mechanical properties of 3D printed concrete (ILS-mech).&nbsp; The study was prepared in 2022 by a preparation group leading to a Study Plan which the TC approved on 29 November 2022 (<a href="https://doi.org/10.14459/2023mp1705940">https://doi.org/10.14459/2023mp1705940</a>). The ILS-mech was performed in 2023. The data was collected using a pre-prepared spreadsheet template. For data management, a database was derived and set-up in openBIS. The underlying Postgres database of openBIS was exported to the here-published SQLite database for sharing without maintaining a server. The structure of the database is described in (<a href="https://doi.org/10.1617/s11527-025-02650-9">https://doi.org/10.1617/s11527-025-02650-9</a>). The results are discussed in three associated papers focusing on the overall outcomes and evaluation of the procedures (<a href="https://doi.org/10.1617/s11527-025-02686-x">https://doi.org/10.1617/s11527-025-02686-x</a>), the compressive test results (<a href="https://doi.org/10.1617/s11527-025-02688-9">https://doi.org/10.1617/s11527-025-02688-9</a>), and the tensile test results (<a href="https://doi.org/10.1617/s11527-025-02687-w">https://doi.org/10.1617/s11527-025-02687-w</a>).</p> <p>contact via freek.bos@tum.de</p>
