What is the density of quartz sand

The ratio of weight to volume determines the density of sand

Grain sizes

Several properties lead to the specific gravity of sand. One starting point is the specific gravity of the sand. The grain size also has an influence on the density, with grain sizes between 0.063 and two millimeters being referred to as sand. Smaller grain sizes belong to the silt group, the consistency group between sand and clay. Larger grains are classified as gravel.

Water content and moisture

The density is also influenced by the water content of the sand. The higher the proportion, the lighter and therefore the lower the density of the sand. Moisture leads to stored air and chemical hydrogen formation, which creates larger spaces between the grains of sand. The same principle works with wet sand, which also loses density.

Washed sand

One method of increasing the specific gravity of sand is by washing. Washed sand with the same grain size is cleaned of foreign "fillers" by washing out and the individual grains of sand move closer together. The larger number of grains of sand in the same volume increases the weight and thus the density.

Density of classic types of sand

  • Washed sports sand for beach volleyball 1200 kilograms (kg) per cubic meter (m³)
  • Unwashed crushed sand 1520 kg / m³
  • Screed sand 1590 kg / m³
  • Wall sand 1500 to 1600 kg / m³
  • Quartz sand 1430 to 1470 kg / m³
  • Double washed Rhine sand 1500 kg / m³
  • Washed play sand 1320 kg / m³

Washed normal sand has the following densities:

  • With grain sizes from zero to one millimeter 1320 kg / m³
  • Zero to four millimeters 1540 kg / m³
  • Zero to six millimeters 1600 kg / m³
  • Zero to eight millimeters 1620 kg / m³

Deviations in the single-digit kilogram range can result from different mixing proportions of the grain sizes.

If you want to calculate the weight of sand to fill a pit or other space, you often have to convert the density to tons. For example, if you need a cubic meter of sand with a density of 1500 kg / m³, the sand weighs 1.5 tons.
