"Web3. Ideal and non-ideal porous solids. In an ideal porous solid, the solid phase is microscopically homogeneous and isotropic, and the pore space is fully connected. At the grain level, micro-homogeneity implies that the material is made of the same mineral and micro-isotropy suggests that the material deforms the same in all directions.
