More Details· Bulk Density Of Aggregates. Jalal Afsar July 30, 2012 Concrete Strength No Comments. Bulk density of aggregates is the mass of aggregates required to fill the container of a unit volume after aggregates are batched based on volume. It depends on the packing of aggregate i.e. Either loosely packed aggregates or well dense compacted aggregates.

More Details· For gravel, the bulk density can be higher up to 130 lbs/cf as the voids are filled with sand and smaller (than 3/4") stone. We need to know the gradation of the gravel to answer this question (which has yet to have been asked. However, it is up to Mr. Guest to clarify this point and he seems to have stepped away.

More DetailsIf soil has >10 % gravel or the stones are >2 cm conventional bulk density readings will be inaccurate, as most coarse fragments have bulk densities of 2.2–3.0 g/cm 3 (McKenzie et al., 2002). This is important to recognise when using bulk density measurements to calculate nutrient levels on an area basis, as an over-estimation will occur.

More DetailsThe specific gravity of anthracite (1.4–1.45) is lower than that of sand (2.6–2.7), bulk density is about 0.73 g/cc and voidage is about 50%. The apparent bulk density after compaction during filtration is approximately 0.79 g/cc. The lighter anthracite is placed on denser sand.

More DetailsAnd 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.

More Details· Determination of bulk density of aggregates: (ASTM C-29/C-29M) Significance: This test method is used to determine the bulk density of the given specimen. During the concrete mix design, when the aggregate is to be batched by volume or by weight, then it becomes necessary to know the mass of the aggregates that will fill the container of unit ...

More DetailsBulk 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.

More DetailsBulk density of aggregates is the mass of aggregates required to fill the container of a unit volume after aggregates are batched based on volume. It depends on the packing of aggregate i.e. Either loosely packed aggregates or well dense compacted aggregates.

More DetailsBulk density is equal to mass if the volume is unit. In the above definition, the volume contains both aggregates along with voids between aggregate particles. The approximate value of bulk density for aggregate usually used for normal-weight concrete varies between 1200-1750 Kg/m 3 or 75 to 110 lb/ft 3. Relative Density or Specific Gravity of ...
