contact usBulk density (or density in a mass) is the weight of the material including the intergranular air space in unit volume. This is determined with the help of the test weight apparatus (Fig. 13.12).The container comes in a litre or 500 ml capacity. The grains are allowed to fall into the container from a standard height at a standard flow rate through the funnel.
contact usRoot growth, in general, starts to be restricted when the bulk density reaches 1.55 to 1.6 g/cm 3 and is prohibited at about 1.8 g/cm 3. Tillage can increase bulk density if it breaks down aggregates and allows soil separates to pack more tightly. Adding organic material decreases bulk density because organic material has a lower bulk density.
contact usSummary. Laboratory tests have shown that variation of grading within the limits permitted by the British Standard 882:1944 for concrete aggregates results in differences of as much as 12 lb/cu.ft. in the compacted bulk density of coarse aggregates, and 13 lb/cu.ft. in Class A and 31 lb/cu.ft. in Class B fine aggregates.
