Most manuals and standards for soil BD determina-tion do not specify one method but describe a range of different methods (ISO, 1998; Smith and Mullins, 2000). Because BD is defined as mass per unit volume, it is most often determined by measuring the oven-dry weight of a known sample volume (core method).

If you don’t know the weight, one of the easiest ways to get a density is to measure out a cubic foot. NOTE - It’s important to pull material from a few feet below the surface as that will be a more accurate representation of the pile’s moisture level throughout. Once you have a cubic foot a material measured, find the weight minus the ...

The normative characteristic of the average bulk density for hollow stones should not exceed 1 650 kg / m³, for full bodies - 2,200 kg / m³. Wall stones in terms of average density (and, in addition, thermal conductivity) are considered effective (density up to 1,400 kg / m³), conditionally effective (1,400-1,650 kg / m³) and heavy (above 1,650 kg / m³).
