The definition of the bulk density in Equation 1, addressing explicitly the total mass of solids and the total volume it occupies, indicates that it is a physical macro-property related to both soil texture and structure. Soil texture corresponds to the relative amount of sand, silt, and clay components of the solid phase.
Youd (1973) studied the factors affecting the maximum and minimum densities of sands. It was found that properties like particle size range, shape and changes in the gradation curve affect the density of sand. The void ratios too were found to decrease with increase in uniformity coefficient, which represents the particle size range.

The density of sand in kg/m³ usually ranges from 1600 to 1800 kg/m³ for dry sand. However, the density can vary significantly depending on factors like moisture content, compaction, and purity. For example: Dry, compacted sand typically …
The density of sand can vary based on factors such as relative density, gradation, and compaction energy. Research by Mujtaba et al. focused on sandy deposits and found in-situ bulk density ranging from 13.24 to 18.44 kN/m3, with dry unit weight varying between 12.22 and 19.17 kN/m3. Szajna and Lechocka highlighted the sensitivity of density index to measurement …

The objective of the study is to use a 3D Acoustic Doppler Velocimeter (ADV) to gauge the typical flow and turbulence characteristics within a non-uniform open channel. The findings of experimental examinations of the subcritical flow along the channel are presented in this work. The behavior of sand grains in turbulent open channel flow across porous and rough …
The density of sand can be influenced by several factors, including: Mineral Composition: The mineral composition of sand can significantly affect its density.Different minerals have varying densities, with heavier minerals such as magnetite (5.18 g/cm³) having a higher density than lighter minerals like quartz (2.65 g/cm³).

The impact of particle crushing and relative density on calcareous sand is substantial; however, relevant studies, particularly in constitutive modelling, remain limited. To …
Several factors influence sand density, including moisture content, compaction, grain size, and mineral composition. These factors affect sand's stability, percolability, and load-bearing capacity. Wet, compacted sands are …
The type of sand, grain size, moisture content, and compaction are factors that impact the density of sand. ... Sand density is lighter than soil density which can affect specific soil properties like water retention and nutrient …
persistent shear band in a symmetrically loaded localizing sand body. We combine experimental imaging on rectangular sand specimens loaded in plane strain compres-sion with mesoscale finite element modeling on symmetrically loaded sand specimens to show that spatial heterogeneity in density does have a profound impact on the persistent shear band.
Sand and dust storms (SDS) frequently hit northern China and adversely impact both environment and health. The carbonaceous components, inorganic elements, water-soluble ions, and meteorological parameters of several severe SDS episodes have been measured in a supersite in Tianjin, which is a big and representative city located in SDS transmission pathway …

The results revealed that the K0 of coral sand decreased with an increase in effective stresses, while the impact of the initial relative density on K0 was more obvious.
Increasing bacterial optical density enhances the effectiveness of MICP in reducing sand erosion, thereby lowering the cumulative erosion percentage. At a low bacterial optical density (OD 600 = 0.5), erosion is characterized by a short duration and high erosion rate, with a cumulative erosion percentage of 72.0 % after 10 min ( Fig. 7 a and b ...
