PCT reconstruction of segmented grains of the hemihydrate and gypsum during the dissolution–precipitation process. The reconstructions are reported following the time evolution (indicated by the blue dashed arrow), from the dry conditions (presence of hemihydrate only) to the end of the hydration (presence of gypsum only). The PCT reconstructions are coupled with the crystallographic orientations calculated for the two specific grains from the s3DXRD analysis. On the right is a schematic representation of the transformation from the hemihydrate structure to the gypsum structure. Legend: grey balls – Ca atoms; yellow balls – S atoms; red balls – O atoms; white balls – water molecules.
