The Density of Sand utility returns sand density based on sand conditions (wet/dry in bulk / packaged).. The density of the sand is affected if the sand is compacted (bulged) or loose and if it is wet or dry.When packed, the grains of sand are forced to form a narrower formation, and more matter is in the volume.. Natural sand i.e. locally available River sand having a bulk

Inherent Factors Affecting Bulk Density and Available Water Capacity Inherent factors that affect bulk density such as soil texture cannot be changed. Bulk density is dependent on soil organic matter, soil texture, the density of soil mineral (sand, silt, and clay) and their packing arrangement. As a rule of thumb,
Bulk density of coarse aggregate concrete Significance and Use 4.1 This test method is often used to determine bulk density values that are necessary for use for many methods of selecting proportions for concrete mixtures. 4.2 The bulk density also may be used for determining mass/volume relationships for conversions in purchase agreements.

If soil has 10 % gravel or the stones are 2 cm conventional bulk density readings will be inaccurate, as most coarse fragments have bulk densities of 2.23.0 g/cm 3 (McKenzie et al., 2002). This is important to recognise when using bulk density measurements to calculate nutrient levels on an area basis, as an over-estimation will occur.
