PET/CT during degradation processes at the cement-clay interface and derivation of process parameters

Observation of degradation processes is complicated by the heterogeneous nature of the process. Better process understanding requires methods for both monitoring the fate of chemical species (mobile phase) and structural alterations (stationary phase). In the past decade, we empowered positron emission tomography (PET) for quantitative transport visualization in geological media – GeoPET. It has an unrivalled sensitivity and robustness for quantitative, non-destructive, spatio-temporal concentration measurements cPET(x,y,z,t). CT adds structural information.
