What is the range of specific gravity of fine aggregate?

The specific gravity of aggregates normally used in construction ranges from about 2.5 to 3.0 with an average value of about 2.68.

What is specific gravity of coarse aggregates?

The specific gravity of aggregates normally used in road construction ranges from about 2.5 to 3.0 with an average of about 2.68. Water absorption shall not be more than 0.6 per unit by weight.

What is bulk specific gravity of fine aggregate?

Bulk SSD Specific Gravity: The ratio of the weight in air of a unit volume of aggregate, including the weight of water within the voids filled to the extent achieved by submerging in water for approximately 15 hours, to the weight in air of an equal volume of gas-free distilled water at the stated temperature.

What is specific gravity test of aggregate?

Overview. The coarse aggregate specific gravity test (Figure 1) is used to calculate the specific gravity of a coarse aggregate sample by determining the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. It is similar in nature to the fine aggregate specific gravity test.

What is the fine aggregate?

Fine aggregates are essentially any natural sand particles won from the land through the mining process. Fine aggregates consist of natural sand or any crushed stone particles that are ¼” or smaller. This product is often referred to as 1/4’” minus as it refers to the size, or grading, of this particular aggregate.

Is 2720 specific gravity?

This standard ( Part III ) deals with the method of test for determination of specific gravity of soils which finds application in finding out the degree of saturation and unit weight of moist soils. The unit weights are needed in pressure, settlement and stability problems in soil engineering.

What is the size of fine aggregates a 4.75 mm B 4.75 mm C 4.75 mm D 12mm?

4. What is the size of fine aggregates? Explanation: The size of the fine aggregates is less than 4.75mm because it passes from 4.75 mm sieve at its lowest so there is no chance for more than 4.75mm in its size. 5.

What is the maximum size of fine aggregate?

Introduction to fine aggregates: The maximum size used is 80 mm and the range of 80 mm to 4.75 mn is known as coarse aggregate and 4.75 to 150 µm is called fine aggregate. Size 4.75 mm is common for both fine and coarse fractions.

What is fine aggregate with example?

Fine aggregates are the particles that pass through 4.75 mm sieve and retain on 0.075 mm sieve. Coarse aggregates are the particles that retain on 4.75 mm sieve. Sand, surki, stone screenings, burnt clays, cinders, fly ash, etc are used as fine aggregate in concrete.

Is 2720 a part XL?

This part [IS: 2720 ( Part XL)-19771 deals with the method of test for the determination of free swell index of soils. The possibility of damage to structures due to swelling of expensive clays need be identified, at the outset, by an investigation of those soils likely to possess undesirable expansion characteristics.

What is bulk specific gravity?

bulk specific gravity. The ratio of (a) the mass of a volume of material (including the mass of the water within the voids, but excluding the voids between particles) at a stated temperature to (b) the mass of an equal volume of distilled water at a stated temperature.

What is the specific gravity of a solid?

Specific gravity (sg) is properly defined as the ratio of the density of a substance (typically a liquid or a solid) compared to the density of water. Water has a density of 1.0 g/cc at normal pressure and temperature, so the specific gravity of a substance that is 1.6 times heavier than water would be equal to 1.6.

What is the specific gravity of gravel?

In Imperial or US customary measurement system, the Gravel, Regular density is equal to 84.03 pound per cubic foot [lb/ft³], or 0.78 ounce per cubic inch [oz/inch³] . Gravel, Regular density is equal to 1346 kg/m³ or 84.028 lb/ft³ with specific gravity of 1.346 relative to pure water.

What is the specific gravity of concrete?

Specific gravity is the ratio of the weight of a cubic foot of a material to the weight of a cubic foot of water, which is 62.4 pcf. Therefore, the specific gravity of a typical concrete mix is 145/62.4 or 2.32.
