What is the density of a coarse aggregate?
Answer (1 of 2): thanks for ask bro… Coarse Aggregate in general should consist of natural occurring stones (crushed, uncrushed or broken), riverbed single or pit gravel. It should be hard, strong, dense, durable, and clean. It must be free from veins, adherent coatings and injurious amounts of

Density of Aggregate
The relative density (specific gravity) of an aggregate is the ratio of its mass to the mass of an equal volume of water. Relative Density = Mass of the Aggregate / Mass of equal volume of water. Key Features: Most aggregates have a relative density between 2.4-2.9 with a corresponding particle (mass) density of 2400-2900 kg/m3 (150-181 lb/ft3).

Crushed Concrete Density?
Hangontight....With pieces that large, your density will not be high...likely on the order of 90 to 100 pcf for the crushed concrete. If it were crushed in the manner of a graded aggregate base material, the density would be upwards of 120+ pcf. RAP will be somewhere in the 90 to 95 pcf range, depending on gradation.

What is bulk density and % of voids of fine aggregates
And percentage of voids present in fine aggregate is calculated with the help of specific gravity of fine aggregate and their Loose bulk density by the following formula. % of voids = { (Gs _R)/Gs}×100. Where Gs = specific gravity of fine aggregate and their value is 2.62. R = loose bulk density of fine aggregate = 1.398 kg/L.
