Sand is one of the fundamental ingredients in concrete. Density is an important parameter for sand. For sand, density is determined by multiplying the relative density (specific gravity) of the sand times the density of water.

Bulk Density of Sand

The bulk density or unit weight of sand is the mass or weight of the sand that required to fill a container of a specified unit volume.

Bulk Density of sand = Mass od sand/volume

Key Features:

  • If the volume is unit then, Bulk Density= Mass.
  • Unit in kg/m3 or lb/ft3.
  • In this definition, the volume is that contain both the sand and the voids between sand particles. 
  • The approximate bulk density of sand that is commonly used in normal-weight concrete is between 1520-1680 kg/m3 (95-105 lb/ft3[1]
  • Here, Standard test method for determining the bulk density of sand is given in ASTM C 29 (AASHTO T 19). [2]
