“…The angle of repose ( ϕ cv ) is almost constant with d 50 and U (see Fig. 9c, d), and the experimental values are in good agreement with those measured on other granular materials with permanent grains [27]. Figure 10 shows some general characterisation of the evolution of grading with loading, using data obtained from sam- Figure 10a, b shows the grain size distribution by weight obtained after isotropic, one-dimensional and triaxial compression after reaching either measured or calculated final values of the mean effective stress equal to 175 and 700 kPa, respectively.…”

“…The loosest packing was obtained by pouring the material into a mould using a funnel with drop height of zero; the densest packing was obtained by vibrating the material in the mould at very low energy to avoid breakage of the grains. The extent of the intergranular voids ratio, e max −e min , for crushed LECA at different values of U and d 50 by volume, were compared with those reported by [27] for a wide range of granular materials, including natural sands, light- Fig. 9a, b); however, the values obtained for crushed LECA are much larger than those obtained for other granular materials.…”

The mechanical behaviour of granular materials depends on their grading. Crushing of particles under compression or shear modifies the grain size distribution, with a tendency for the percentage of fine material to increase. It follows that the frictional properties of the material and the critical states are modified as a consequence of the changes in grain size distribution and the available range of packing densities. This paper illustrates an extended experimental investigation of the evolution of the grading of an artificial granular material, consisting of crushed expanded clay pellets under different loading conditions. The changes of grading of the material after isotropic, one-dimensional and constant mean effective stress triaxial compression were described using a single parameter based on the ratio of the areas under the current and an ultimate cumulative particle size distribution, which were both assumed to be consistent with self similar grading with varying fractal dimension. Relative breakage was related to the total work input for unit of volume. For poorly graded samples, the observed maximum rate of breakage is practically independent of initial uniformity. Further

“…Research on soil mechanics, for several decades, revealed that the amount of fines in a sand-silt mixture has significant effects on its mechanical properties (e.g. Selig and Ladd, 1973;Aberg, 1992;Miura et al, 1997;Cubrinovski and Ishihara, 2002;Bobei et al, 2009;Peters and Berney 2010;Fuggle et. al 2014).…”

“…Some studies have been devoted to developing procedures to determine the particle shape properties (Masad and Buton, 2000;Rao and Tutumluer, 2000;Alshibli and Alsaleh, 2004;Masad et al, 2005;Al-Rousan et al, 2007;Arasan et al 2010b). Others have focused on the effect of particle shape on maximum and minimum void ratios (Holubec and D'Appolonia, 1973;Youd, 1973;Miura, 1997;Lade et al, 1998;Cubrinovski and Ishihara, 1999;Cubrinovski and Ishihara, 2002;Yilmaz, 2009;Arasan et al, 2010c) and internal friction angle of granular soils (Chan and Page, 1997;Santamarina and Cho, 2004;Cho et al, 2006.

Due to their irregularity, the shape of particles is not accurately described by Euclidian geometry. However, fractal geometry uses the concept of fractal dimension, D R , as a way to describe the shape of particles. In this study, the fractal dimensions and shape properties of particles were determined using image analysis. Exponential relationships between the fractal dimension and roundness, sphericity, angularity, convexity were described. A set of empirical correlations were also presented which clearly demonstrated the link between fractal dimension and shape properties of particles. Additionally, a new classification chart proposed for use in describing and comparing particle shape and fractal dimension.
