Density of Construction Materials in kg/m3 and lb/ft3 ...

Density is also called as unit weight of substance. It is represented by symbol called row ( p). Density represents the degree of compactness of material. If the material is of more density, it is more compacted material. Density is defined as the ratio of mass to volume. p = m/v Units = kg/m 3 or lb/ft 3 Conversion: 1 kg/m 3 = 0.624 lb/ft 3.

As per the definition given in the 'IS: 2386 (Part III) – 1963', (Indian Standard- Methods of Test for Aggregates for Concrete – Specific Gravity, Density, Voids, Absorption and Bulking), the specific gravity of coarse aggregates is the weight of the aggregates dried to constant weight in an oven at 100°C divided by its absolute volume including the natural voids within the aggregate ...

"DETERMINATION OF BULK DENSITY OF ROCK CORE USING STANDARD …

Density is a basic property of a material that is equal to the objects mass divided by its volume. However the determination of an accurate density for some rock materials can difficult. This difficulty comes from many sources such as irregular volume, porosity, moisture content of the material, permeability of the material and the lack of a clear definition of density itself.
