Density is also called the unit weight of a substance. It is represented by a symbol called a line (p). Density represents the degree of compactness of a material. If the material is of higher density, it is more compacted material.
The density of construction materials is their Mass per unit volume of materials. It is expressed in kg / m3 or lb / ft3 and shows the compactness of the construction material.
The density can be expressed as
- p = m/V = 1/v
- p = density
- m = mass
- V = volume
- v = specific volume
Sand Density
The density of sand utility returns sand density based on sand conditions.
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 density of 1.71 kg/m3 was used for the construction (specific gravity is 2.65). This sand has the Fineness modulus of 5.24.
When the sand is wet, the water is in the sand, also affecting the total matter in the volume. The average density of the different sand conditions is as follows:
- Loose Sand: 1442 kg / m3. It is dry sand that has been moved or agitated to loosen the natural packaging process.
- Dry Sand: 1602 kg / m3. It is sand in its undisturbed natural form, where it has been partially compacted by rain and gravity over time, but is now dry
- Packed Sand: 1682 kg / m3. Sand that has been packed manually or mechanically (compacted)
- Wet sand: 1922 kg / m3. This is the sand that has been in a natural and naturally compressed environment that is now wet.
- Wet packed sand: 2082 kg / m3. This is compacted sand that is also almost saturated with water.
