Dataset for poster presentation: Sorption Measurements in Cement Paste using GARField MR Imaging

This dataset supports the results included in the poster presentation 'Sorption Measurements in Cement Paste using GARField MR Imaging', Ors Istok, P. J. McDonald, D. A. Faux, A. M. Gajewicz-Jaromin, at the 39th Cement and Concrete Science Conference, 9-10 September 2019, University of Bath, UK.

See the file "Metadata Documentation.docx" for details of the dataset.

Moisture transport in cementitious materials is well known to be anomalous in so much as it does not evolve with t 0.5 dependency. Time dependent cement microstructure has been observed by Gajewicz et al and Maruyama et al during de/sorption using NMR relaxometry.

This project aims to better understand links between sorption, microstructure and transport using high spatio-temporal resolution GARField MRI. The obtained data is fitted to a new transport model with a time dependent transport coefficient.

The preliminary results provide a strong indication that the model is able to link transport and dynamic changes in microstructure linked to de/sorption. Future work will look to better parametrise the model and also to compare first and second cycle de/sorption.

The conference proceedings are published by University of Bath in association with Cementitious Materials Group, Institute of Materials Minerals and Mining, London, UK.
