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

  • 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
