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.

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.

description: About this Version

This Version of the data set contains the data of the manuscript as re-submitted to Cement and Concrete Research on 31st January 2025.

During Review, changes have been made in the details of implementation of the micromechanical model. The changes in the micromechanical model did not influence any of the conclusions drawn.

The following data has been updated compared to the previous version:> 05 Stiffness Predictions
