What is the difference between specific gravity apparent specific gravity and true specific gravity?
Answer:True specific gravity is the ratio of unit weight of soil solids to that of water. But apparent specific gravity is the ratio of unit weight of total soil mass to that of water.
What is the difference between apparent density and bulk density?
Apparent density is the bulk density of the powder. It provides the mass per unit volume of loose packed powders. A change in apparent density can also indicate a change in the surface roughness of the powder; for example, atomization satellites may reduce apparent density.
What is the bulk specific gravity?
Bulk Specific Gravity (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 gas-free distilled water at the stated temperature.
What is the difference between bulk specific gravity and theoretical maximum specific gravity?
Percent air voids is calculated by comparing a test specimen’s bulk specific gravity (Gmb) with its theoretical maximum specific gravity (Gmm) and assuming the difference is due to air. This bulk specific gravity is then compared to the most current theoretical maximum specific gravity to determine air voids.
What is the difference between bulk specific gravity and SSD bulk specific gravity?
The difference between Gsb and bulk (SSD) specific gravity is the weight of aggregate used in the calculations. The difference between these weights is the weight of absorbed water in the aggregate’s permeable voids. Both use the same aggregate volume.
What is the difference between particle and bulk density?
Bulk density is defined as the dry weight of soil per unit volume of soil. Bulk density considers both the solids and the pore space; whereas, particle density considers only the mineral solids.
What is difference between bulk density and bulk unit weight?
Density is a measure of the quantity of mass in a unit volume of material. Unit weight is a measure of the weight of a unit volume of material. Both can be used interchangeably.
Why is apparent specific gravity greater than bulk specific gravity?
The bulk or volume specific gravity is based upon the volume as a whole–i.e., the solid material with all included pores. The apparent specific gravity is based upon the volume of the solid material plus the volume of the sealed pores.
What is bulk specific gravity used for?
The bulk specific gravity test is used to determine the specific gravity of a compacted HMA sample by determining the ratio of its weight to the weight of an equal volume of water.
Which of the following has maximum specific gravity?
Detailed Solution
| Material | Specific gravity |
|---|---|
| Mercury | 13.56 |
| Depleted uranium | 19.1 |
| Gold | 19.3 |
| Osmium | 22.59 |
Which is less apparent specific gravity or bulk specific gravity?
Since it includes the water permeable void volume, bulk specific gravity will be less than apparent specific gravity. It is formally defined as the ratio of the mass of a unit volume of aggregate, including the water permeable voids, at a stated temperature to the mass of an equal volume of gas-free distilled water at the stated temperature.
What’s the difference between dry and saturated bulk gravity?
Dry Bulk Specific Gravity does not take into account for anything getting into the permeable or impermeable voids of say a stone by water for instance. Saturated Surface Dry Bulk Specific Gravity takes into account for anything getting into the permeable voids only of say a stone by water.
What is the specific gravity of an aggregate?
Specific gravity is density of any material with respect to standard material. Higher the density of any material with respect to standard material will have specific gravity. In general specific gravity of an aggregate varies from 2.65 to 2.90.
How is the specific gravity of water determined?
The bulk specific gravity test is used to determine the specific gravity of a compacted HMA sample by determining the ratio of its weight to the weight of an equal volume of water. Dry (no water in sample). Saturated surface dry (SSD, water fills the HMA air voids).
