Density of Construction Materials

Density of Construction Materials

~ The density of construction materials is the ratio of mass per unit volume.

~ It shows the compactness of construction material.

~ It is also called the unit weight of the substance or material.

~ Its unit is kg/m³ or lb/ft³.

~ It is represented by row (p).

~ Lower dense materials occupy more volume as compared to high dense materials.

~ Mathematically;

           p = m/v

~ Note:

1 kg/m3 = 0.624 lb/ft3

~ The density of construction material determines the sinking property of material which plays a vital role in the design and construction of dams, foundations, etc.

~ The value of density is found for materials, not quantities. So different materials have their own density.

~ The density of  construction materials used in the construction are :
