SUMMARY Based on self organized growth, a self-similar geometrical model of rock materials is established. The structural mode of the internal surface is carried over to the three-dimensional structure of the pore space and solid phase, which can be described as a fractal network. It is characterized by the fractal dimension of surface, which can be measured by physical and stereological methods. From this, the fractal behaviour of other geometrical properties, relevant for physical processes, such as porosity, number of solid connections, tortuosity and constrictivity of the capillary system and of the solid phase can be derived. |
