ABSTRACT
The geotechnical properties of sand deposits are heavily influenced by their physical characteristics, making their characterization essential. By subjecting 15 specimens to isotropic triaxial tests and by using a simple table scanner to collect 2D-oriented projections of the sand grains, the study aims to present a comprehensive physical characterization of Foulum high quartz glaciofluvial sand, with an emphasis on its implications on the shear behaviour and drained peak friction angle φ′p of the tested sand. The results revealed the multifaceted nature of granular material behaviour. In particular, the stress dependency and initial conditions emerged as extremely important, in line with previous research. The study also highlights the importance of the sample size when considering particle shape (sphericity in particular) on the geotechnical properties.
