Objective Determination of unit weight or bulk density and void of aggregates. Equipments Name Capacity 1. Balance Sensitive to 0.5 of weight of material 2. Cylindrical metal measure Of 3 litre capacity for fine aggregate Of 15 litre capacity for aggregate upto 40mm 3. Tamping rod 16 mm dia. and 60 cm long Sample Preparation
The higher the bulk density, the lower or higher the pore space , what do we assume 2.65 gcm3. Bulk density affects Water movement, air exchange, root growth. Do fine textured or coarse textured soils have lower bulk densities better structured in aggregates. Common range for fine textured soil Db 1.01.60 gcm3. Common
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.
Bulk specific gravity of aggregates can be defined as the ratio of ovendry weight of the aggregate to the bulk volume of the aggregate particles. It is the ratio of mass of the substance at the stated temperature to the mass of the volume of the distilled water at the specified temperature.
Coarse Aggregate Gravity Apparatus A. Bulk Specific Gravity Gsb also known as Bulk Dry Specific Gravity The ratio of the weight in air of a unit volume of aggregate at a stated temperature to the weight in air of an equal volume of gasfree distilled water at a stated temperature Figure 2.
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
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
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
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.
Bulk density mass of soil total volume. Let39s plug in our figures 800 kg 0.5 m 3 1600 kgm 3. So, the bulk density of our soil sample is 1,600 kgm 3. Here39s another example A soil
The bulk density is the mass of the material related to a specific volume and for cement is normally expressed as kilograms per cubic metre. The bulk density reflects the volume taken up by the cement plus any air trapped between the p

Specific Gravity Relative Density of a Blended Aggregate The specific gravity of a blended aggregate is not simply the weighted average of the specific gravities of the individual components. To derive an appropriate equation, lets assume a blend of two aggregates A and B.
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 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.
