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.

Void ratio - Geotechdatafo

Where V_v is the volume of the voids (empty or filled with fluid), and V_s is the volume of solids. Void ratio is usually used in parallel with soil porosity (n), which is defined as the ratio of the volume of voids to the total volume of the soil. The posoity and the void ratio are inter-related as follows: e = n /(1-n) and n = e / (1+e) The ...
