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
The bulk density values determined based on this test can be used for many methods of selecting proportions for concrete mixtures. Added to that the evaluation of the percentage of voids between particles in fine coarse or mixed aggregates is dependent on the bulk density.
Fine aggregate is the essential ingredient in concrete that consists of natural sand or crushed stone. The quality and fine aggregate density strongly influence the hardened properties of the concrete.
Bulk density is the mass of a unit volume of material in its natural statewith pores and voids. For cement portland cement density 2.9-3.1 gcm3 For sand bulk density is 1450-1650 kgm3 and the bulk density of aggregate depends upon their packing the .
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.

Bulking of fine aggregate 3. The bulk density or unit weight of an aggregate is defined as mass of the aggregate per unit volume .it is expressed in kg/liter.
Types of bulk density of fine aggregate. Bulk density of fine aggregate is egorised into two egories depending on how they can poured and settle into cylindrical metal measurement unit. 1 Loose bulk density. 2 Rooded bulk density. 1 Loose bulk density:- it is the ratio of mass of loosely packed fine aggregate without Tamping or rooded ...
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.
