Data for: Deriving early hydration cement paste phase assemblage, microstructure development and elastic properties using thermodynamic simulation and multi-scale material modeling

Description DATA REPOSITORY FOR Title: Deriving early hydration cement paste phase assemblage, microstructure development and elastic properties using thermodynamic simulation and multi-scale material modelingBy: Eva Jägle, Jithender J. Timothy, Daniel Jansen, Alisa MachnerPublished in: Cement and Concrete ResearchLink: doi.org/10.1016/j.cemconres.2025.107830 This dataset presents the data of the paper 'Deriving early hydration cement paste phase assemblage, microstructure development and elastic properties using thermodynamic simulation and multi-scale material modeling' submitted to and accepted by Cement and Concrete Research. The dataset follows the structure of the paper such that the calculations described therein can be reproduced. Data is available on three types of cement: Two ordinary Portland cements of different grinding fineness (CEM I 42.5 R und CEM I 52.5 R) and one limestone-containing blended cement (CEM II/A-LL 42.5 R). The data refer to the first 24 hours of hydration and temperature conditions of 20 °C (for CEM I 42.5 R, CEM I 52.5 R, CEM II/A-LL 42.5 R) and 35 °C (for CEM I 52.5 R). All data were retrieved for cement pastes with a water-to-cement ratio of 0.45. The dataset contains raw and processed data from quantitative X-ray diffraction, 5PL cement dissolution fitting, thermodynamic simulation with GEMS, multi-scale material modeling, ultrasonic testing and Vicat penetration tests. The data is mainly available in .xlsx files together with short descriptions in ReadMe.txt files.
