Abstract

Wang et al. (2022) have presented a good paper related to estimating the skeleton void ratio of grave–sand mixtures. The most important contribution is that Wang et al. (2022) presented a new relationship to determine the skeleton void ratio and the parameters used in the relationship are easy to be obtained. Their paper related the grain size distribution properties of the coarse and fine materials, namely, coefficient of uniformity of fine material and coarse material and the ratio of the diameter corresponding to 50% of the coarse materials and the fine materials. The method is promising, though the discusser has some observations related to the methods of analysis and definition of coarse and fine materials.
