Summary

Under a microscope, materials are characterized by their three-dimensional (3D) microstructure formed by components such as pores, cracks, and particles; and their mechanical and hydrological properties are highly related to their microstructure. In order to discuss the mechanics of geomaterials based on their microstructure, details of the 3D microstructure are needed. X-ray CT, especially microfocus X-ray CT, is a powerful tool to detect microstructures using a non-destructive method. However, it is difficult to evaluate microstructures using reconstructed 3D images. We successfully evaluated 3D microstructural anisotropy of porous, granular, and fibrous materials using the multidirectional scanning line (MDSL) method based on simple image analysis. The stereo-net projection plotted using results of the MDSL method allowed visualization of structural anisotropy of such materials, and identified the principal axis of structural anisotropy.
