In dense sand, there is a considerable degree of interlocking between particles and this interlocking must be overcome before shear failure can take place.
Get PriceThere are two basic measures of density or unit weight applied to soils: Dry density is a measure of the amount of solid particles per unit volume. Bulk density is a measure of the amount of solid + water per unit volume. The preferred units of density are: Mg/m , kg/m or g/ml. The corresponding unit weights are: Also, it can be shown that

Get PriceThe density of sand varies according to its conditions ( Dry or Wet or packed). The density of sand may change if it is in a dry or wet condition as well as a loose and compacted state. When sand is packed, sand particles are forced to form a narrow disposition, resulting in more material in the volume.
