SEM-EDAX element maps (grey-scale) of Ca (left), Mg (centre), S (right) of 2.2-year samples (smaller areas) and 4.9-year samples (merged long maps). The interface OPC-Opalinus Clay is marked in red. See text for explanation of zones in cement matrix (green lines) and in claystone (blue line). Lower images radiographic images of 14C-MMA impregnated samples (see Sect. 4.3.3). Red line marks the interface. The small dimension is 20 mm
