Density of Cement, Sand and Aggregate
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
Where
- p = density [kg / m3], [slugs / ft3]
- m = mass [kg], [slugs]
- V = volume [m3], [ft3]
- v = specific volume [m3 / kg], [ft3 / slug]
- Conversion: 1 kg / m3 = 0.624 lb / ft3
