Abstract

© The Authors, published by EDP Sciences, 2017. Grain breakage is of paramount importance for understanding the behaviour of granular materials used in various engineering applications, such as pavements, roads, rail tracks, the oil and gas industry, and mineral processing. Changes to grain properties of a uniformly graded sand specimen stemming from breakage during compression were studied with the aid of three-dimensional Synchrotron Radiation-based Micro-Computed Tomography. The fast scanning and high-resolution 4D imaging were utilised to capture images from the interior body of the granular assembly during loading. The fractal distribution of the sand assembly showed that breakage becom..
