Fig. 10From: Bohemian sandstone for restoration of cultural heritage sites: 3D microstructure and mass transport propertiesTop: The local porosity distribution and the local percolation probability evaluated using the measurement cell of special size 85 voxels (Λ* = 220 µm). Bottom: The total fraction of percolating cells as a function of Λ. Direction 3 means that simultaneous percolation in all three principal directions of the cubic measurement cell is observedBack to article page
