cylindrical metal measure used for bulk density and void test of aggregate Sample Preparation. Take the required amount of test sample form the bulk sample using any sample reduction method.; The test is normally carried out on dry material, but when bulking tests are required, material with a given percentage of moisture may be used.

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.

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 is to …

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 ...

The approximate bulk density of aggregate that is commonly used in normal-weight concrete is between 1200-1750 kg/m 3 (75-110 lb/ft 3). Here, the Standard test method for determining the bulk density of aggregates is given in ASTM C 29 (AASHTO T 19). [2] Relative Density of Aggregate [1]

4. Bulk Density Test The bulk density measurement should be performed at the soil surface and/or in a compacted zone (plow pan, etc.) if one is present . Measure bulk density near (between 1 and 2 feet) the site of the respiration and infiltration tests. To get a more representative bulk density measurement of the area, additional samples may ...

The bulk density and void percentage of aggregate can be evaluated using standard test methods of applicable codes such as ASTM C 29/C29M-17a, IS: 2386 (Part 3) – 1963, or BS 812-2:1995. The procedure provided in this article is based on the specification of ASTM standard ( …

Bulk density is the weight of soil for a given volume. It is used to measure compaction. In general, the greater the density, the less pore space for water movement, root growth and penetration, an seedling germination. Facts About Bulk Density. Bulk-density depends upon how densely the aggregate …

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.
