For aggregates, density is determined by multiplying the relative density (specific gravity) of the aggregate times the density of water. Bulk Density of Aggregate [1] The bulk density or unit weight of an aggregate is the mass or weight of the aggregate that required to fill a container of a specified unit volume.

Density of Coarse Aggregate Aggregate which occupy nearly 80 to 85 % volume of concrete are most important part of the concrete or RCC. However, it is well recognize that physical, stone and thermal properties of aggregate substantially influence the properties and performance of concrete.

If a statement is like: A coarse aggregates with higher bulk density, then it means few of the voids can be filled by using fine aggregates and cement. For testing, British Standard (BS 812) has specified the degree of compaction. These are; Loose ( Un-compacted) Compacted; The test will be carried out by using metal cylinder having prescribed depth and diameter and the bulk density

1.1 This test method covers the determination of bulk density (“unit weight”) of aggregate in a compacted or loose condition, and calculated voids between particles in fine, coarse, or mixed aggregates based on the same determination. This test method is applicable to aggregates not exceeding 125 mm [5 in.] in nominal maximum size.

* The bulk density is the mass of the material related to a specific volume and for cement is normally expressed as “kilograms per cubic metre”. * The bulk density reflects the volume taken up by the cement plus any air trapped between the p...

Added to that, the evaluation of the percentage of voids between particles in fine, coarse, or mixed aggregates is dependent on the bulk density. It is worth knowing that, aggregates in stockpiles contain absorbed and surface moisture (the latter affecting bulking), while this test method determines the bulk density on a dry basis.

Rodded Unit Weight of Coarse Aggregate Purpose Determination of the unit weight of coarse aggregates in a compacted condition.

The bulk density is more in compacted state as compared to the loose which shows that the bulk density greatly depends on the degree of compaction or how densely it is packed.; Usually increase in bulk density should be above 15% for coarse aggregate and should be below 15% for fine aggregate, But in our results it is 11.20% for fine aggregate and 11.48% for coarse aggregate.

9. coarse aggregate is placed in a rigid bucket and rodded, 1 answer to coarse aggregate is placed in a rigid bucket and rodded with a tamping rod to determine its unit weight the following data are obtained: a calculate the average dry rodded unit weight btip 3 sampling for laboratory tests relative density specific gravity, bulk dry density

If the particles are of the same size, then it can be packed to a limited extent but when the smaller particles are added, the voids get filled with them and thus the bulk density increases. For a coarse aggregate, a higher bulk density means that there are few voids which are to be filled by the fine aggregate and cement. Thus bulk density

Figure 3.4 Schematic of Dry Lightweight Aggregate 3.5 Aggregate Bulk Density Aggregate bulk density is defined as the ratio of the mass of a given quantity of material and the total volume occupied by it. This volume includes the voids between, as well as the pores within the particles. Bulk density is a function of particle shape, density, size,

09/06/2005· The (150-180) density data comes from a "Design and Control of Concrete Mixtures" book and appears to refer to the "particle" density of aggregate. However, since the aggregate is made up of particles, it is reasonable that the compacted density of the aggregate is between (150-180 lb/ft^3).

Bulk density is a measure of the efficiency with which the powder particles pack together. A good quality powder having “clean” particles with no tails will have a high bulk density. Bulk density and dry flow are dependent on the particle shape, particle size, and particle size distribution of the powder.
