This paper offers a comparative study of two soils- Glauconite and Ottawa F65- utilizing X-ray micro-computed tomography (µCT) scan. The tendency of glauconite sand to transform from coarse to fine-grained material through particle crushing poses challenges in terms of stability and strength, particularly in foundation engineering and offshore site investigation. This paper investigates the particle size distribution and explores the subtleties of particle characteristics. Non-invasive µCT and 3D image analysis are used to measure and compare particle shape parameters: median aspect ratio (0.56 for Glauconite,0.54 for Ottawa F65), median convexity is 0.86 for both soils, and median sphericity (0.81 for Glauconite, 0.83 for Ottawa F65). By drawing comparisons between the statistical data of particle shape parameters from both soils, insights are gained into their morphological characteristics. Additionally, fitted Johnson distributions are provided for 3D Aspect ratio, sphericity, and convexity which may be useful for discrete element method modeling of these soils.
