· 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.
The specific gravity of all other materials are compared to water as a fraction heavier or lighter density. For example, ammonium nitrate has a specific gravity (sg) of 0.73 while dry ammonium sulphate has a sg of 1.13 (1130 kilograms/cubic metre) (see table below)

1.1.1 The unit mass of aggregate in a saturated surface-dry (SSD) condition is intended for use in portland cement concrete mix design. 1.1.2 The dry rodded condition is intended for use in the American Concrete Institute (ACI) design procedure. 1.2 The values given in parentheses (if provided) are not standard and may not be exact
The density of the aggregates is required in mixture proportioning to establish weight-volume relationships. Specific gravity is easily calculated by determining the densities by the displacement of water. All aggregates contain some porosity, and the specific gravity value depends on whether these pores are included in the measurement.

As for the crushed mineral aggregate, the following should be emphasized: All the aggregate grains once belonged to a large rock mass, which disintegrated under the weathering and erosion effects, or it was crushed using machinery. For that reason, many aggregate properties depend on the original rock properties: on its chemical and mineral

· The dry-rodded method was performed by adapting the procedure described in the American standards AASHTO T19 and ASTM C29 to the European standard EN 1097–3, which prescribes aggregate compaction for evaluation of bulk density and air void content in the compacted aggregates, without, however, specifying any procedure.

19.7.3 Density. The density may be bulk density or absolute density. The bulk (dry-rodded) density is measured by compacting a sample of loose aggregate into a container of known volume, and measuring the mass. For the absolute density, the mass is normally measured saturated surface dry (Section 8.4). 19.7.4 Moisture content

DRY RODDED UNIT WEIGHT – The dry rodded unit weight of aggregate is determined by compacting dry aggregate into a container of a known specific volume as per ASTM test method C 29. The weight of the aggregate is measured and divided by the volume of the container to yield the dry rodded unit weight in terms of weight per volume such as pounds ...
Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel. Crushed air-cooled blast-furnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected.
