On the basis of mathematical morphology, the pore size distribution is characterised and the critical pore size is determined for cement paste at different hydration time. The influence of image resolution isinvestigated. The permeability of cement paste can be predicted according toGeneral Effective Media (GEM) theory. Comparison between permeability estimation and experiment results reveals good agreementTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaDruštvo za stereologijo in kvantitativno analizo slike
