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 Uncompacted Compacted The test will be carried out by using metal cylinder having prescribed depth and diameter and the bulk density is to be
Exp 5 Bulk Density. Experiment No. 5 Standard test method for the determination of Bulk Density i.e. unit weight and the voids in aggregates. ASTM C29C29M 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 also depends upon the
This test method determines the specific gravity of coarse aggregates that have been soaked for a period of 15 hours Figure 1. There are four determinations that may be made from this procedure. They are as follows Figure 1 Coarse Aggregate Gravity Apparatus A. Bulk Specific Gravity Gsb also known as Bulk Dry Specific Gravity
Rodded Unit Weight of Coarse Aggregates PURPOSE Determination of the unit weight of coarse aggregates in a compacted condition. This test method is applicable to aggregates not exceeding 15 cm in nominal size. The unit weight so determined is necessary for the design of a concrete mixture by the absolute value method EQUIPMENT AND MATERIALS
thanks for ask bro Coarse Aggregate in general should consist of natural occurring stones crushed, uncrushed or broken, riverbed single or pit gravel. It should be hard, strong, dense, durable, and clean. It must be free from veins, adherent co
In this video I had tried to explain the procedure to find out the density amp air voids of sand in lab as per IS 2386 PART 4. BULK DENSITY AND VOIDS OF COARSE AGGREGATE AS PER IS 2386 PART 3
The approximate bulk density of aggregate that is commonly used in normalweight concrete is between 12001750 kgm 3 75110 lbft 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

Rodded Unit Weight of Coarse Aggregate Purpose Determination of the unit weight of coarse aggregates in a compacted condition. This test method is applicable to aggregates not exceeding 15 cm 6 inches in nominal size. The unit weight so determined is necessary for the design of a concrete mixture by the absolute value method. Equipment
The bulk density and void percentage of aggregate can be evaluated using standard test methods of applicable codes such as ASTM C 29C29M17a, IS 2386 Part 3 1963, or BS 81221995. The procedure provided in this article is based on the specification of ASTM standard ASTM C 29C29M17a. The bulk density or unit weight is the weight
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 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.

Bulk Density of Coarse Aggregate Level 0
As per the definition given in the IS 2386 Part III 1963, Indian Standard Methods of Test for Aggregates for Concrete Specific Gravity, Density, Voids, Absorption and Bulking, the specific gravity of coarse aggregates is the weight of the aggregates dried to constant weight in an oven at 100C divided by its absolute volume including the natural voids within the aggregate
Coarse aggregate is also described by its bulk density, which is a property that can easily be tested in the laboratory. The standard testing procedure for this is the American Society of Testing
