Dec 09, 2020 Specific gravity of fine aggregate is the ratio of the weight of given volume of aggregates to the weight of equal volume of water. Specific gravity of fine aggregates crushed sand and Dolomite Rock Sand were found by using a pycnometer and the test standards were ensured to conform with IS 2386 Part 3 1963. The results are presented in Fig. 1.

General Weights. Solid rock is estimated at 2.5 to 3tons per cubic meter. If rock is crushed into uniform sizes, the presence of open space between the particles causes the load to be lighter -- approximately 1.6 tons per cubic meter. Mixed sizes of crushed rock can range from 1.6 to 2.2 tons per cubic meter.
Higher the specific gravity heavier is the sand particles and higher is the density of concrete. In contrary, a lower specific gravity of sand will result in lower density of concrete. The specific gravity of fine aggregates found in Pune region varies from 2.6 to 2.8. 4. Silt Content
At high temperatures of over 2,200 degrees F 1,200 degrees C, diabase rock specific gravity of 3.0 melts to a glassy type of rock with no specific gravity change. Because this high specific gravity creates havoc on a desired lightweight specific gravity material, it should be avoided totally.
Its specific gravity was 2.72, conforming to Zone-III, and having a fineness modulus of 2.313. Coarse aggregates used in this study were of 10 mm nominal size, having a specific gravity of 2.72. Both aggregates comply with IS 383 22. The grading of both fine and coarse aggregates and their mixture is shown in Table 30.1.
Class 1 Sand and Gravel. Our class 1 gravel is made of sand, clay, and rock. It is brown in color and used mainly for driveways or as a base for construction projects. Class 1 gravel typically has more clay than class 5 gravel. Available for Delivery. Available at Retail Yard. Available at Ogilvie Pit Pits are OSHA regulated.
Base on the weight of the aggregate in the cylinder and a known aggregate specific gravity, the volume of voids as a percentage of total volume can be calculated. As with the FAA test, this loose uncompacted void content is indicative of the relative angularity and surface texture of the sample.

The specific gravity of a solid is the ratio of its mass to that of an equal volume of distilled water at a specified temperature. Because the aggregates may contain water-permeable voids, so two measures of specific gravity of aggregates are used apparent specific gravity and bulk specific gravity.

Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel. Crushed air-cooled blast-furnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or plant. Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected.

Specific Gravity is the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. Water, at a temperature of 73.4 F 23 C has a specific gravity of 1. Specific Gravity is important for several reasons. Some deleterious particles are lighter than the good aggregates.
