title = "On the Optimisation of Cement Microstructure for Nuclear Waste Encapsulation - Probing the Effect of Hydration on Migration Pathways",
abstract = "The hydration process of Ordinary Portland Cement (OPC) has been investigated using 2D Digital Image Correlation (DIC). OPC blended with SrCl2 solution was investigated, with a focus to understand the effect of hydration on microstructure development and associated leaching behaviour. The aim of the study was to establish a link between chemical shrinkage during hydration and OPC microstructure evolution using in-situ imaging techniques. The development of heterogeneous local surface displacements was observed, resulting in a granular displacement pattern at the sample surface. The observed displacement pattern are currently correlated with preferred migration pathways in cement microstructure, by using a combination of in-situ leaching tests with 2D optical and 3D X-ray Computed Tomography (X-ray CT) techniques. X-ray Diffraction (XRD) of cement microstructure after acid leaching has also been explored to optimize in-situ leaching experiments. A general overview of the experimental methodologies is provided in this paper.",
