A comprehensive model for the index void ratios e max and e min of sands is presented. It is
based on a large set of previously published sand properties as well as tests on 25 new …

抄録 Characteristics of the maximum and minimum void ratios of sands and their possible
use for material characterization have been investigated in this study. Data of over 300 …

The limiting void ratios (ie, the minimum and the maximum void ratios) are two important
index properties, which are related to the compressibility, shear strength, and permeability of …

Soil particle roundness (R) and sphericity (S) are two important intrinsic properties that
govern a soil's mechanical behavior. Although R and S have well-established mathematical …

∑ ri/N ð Þ rmax (1) where N is the number of features examined. The first attempt to classify
soil grains by means of roundness is attributed to Russell & Taylor (1937). From visual …

The importance of particle shape, when considering the engineering behavior of sand, has
been well-documented. Angular sands tend to have greater maximum and minimum void …

The minimum and maximum void ratios (e min and e max, respectively) of soils are intrinsic
soil properties related to their particle size distribution (PSD) and particle shape. Different …

The behavior of sand is affected by the content of nonplastic fine particles. How and to what
degree the fines content affects the minimum and maximum void ratios has been studied in …

The goal of this paper is to assess the effects of particle and specific gravity characteristics
(eg shape, size, and specific gravity) on the limiting void ratios e max and e min of granular …

Maximum and minimum density tests, conducted on a variety of clean sands, show that the
minimum and maximum void-ratio limits are controlled primarily by particle shape, particle …
