sand was acquired from a coral island in the South China Sea. The main chemical component of calcareous sand is CaCO 3, and the relative density of the grain skeleton is 2.7. Figure 1 shows a CT scan photograph of calcareous sand, which reveals that the calcareous sand particles are porous, angular, and irregular in shape. e = e 0 − (1) S H 0 ...

For example, by quantifying fractured grains from single sand crushing in Zhao et al. (2015), it was found that fragments are mostly non-star-shaped. Since then, many studies started to use Cartesian-SH to reconstruct CT-scanned shapes of sands or their fragments instead of spherical-SH ( Zhou et al., 2015 ; Su and Yan, 2018 ; Nie et al., 2020 ).
