1. Scope. 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 procedure provided in this article is based on the specification of ASTM standard ( ASTM C 29/C29M-17a). The bulk density or unit weight is the weight per unit volume (mass per unit volume or density). Voids in unit volume of aggregate are the space between particles in an aggregate mass not occupied by solid minerals.

Apr 20, 2018 Dry-rodded unit weight is the mass (weight) of one cubic meter (foot) of dry coarse aggregate that is compacted, by rodding in three equal layers, in a standard container. For any one aggregate the dry-rodded unit weight varies with the size and gradation. Related Posts. Why Column Ties are Used in Concrete Columns . August 22 , 2021 August 22 ...

Feb 14, 2020 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 ...

Unit weight or density is the relationship of aggregate's weight to its volume expressed as weight per unit volume. Values of unit weight/density are used in volumetric-gravimetric calculation. In volumetric batching of concrete aggregates, the unit weight/density should be known to convert weight/mass into loose volume. 4. Resources:

Jul 16, 2017 Normal-weight aggregate: An aggregate with a unit weight of 1520–1680 kg/m3 is classified as normal-weight aggregate. Sand, gravel, and crushed rock belong to this category and are most widely used. Concrete made with this type of aggregate has a bulk density of 2300–2400 kg/m3. It is the main concrete used to produce important structural ...

It is the weight of aggregate needed to fill a unit volume of the container. It helps to convert quantities by weight to by volume. It also indicates the aggregate grading and shape. Bulk Density = Weight of aggregate / Container of unit volume. Unit: Kg/m 3 or lb/ft 3. Essential Points.
