What are coarse aggregates? Aggregates that cannot pass through the IS Sieve of 4.75mm are called coarse aggregates. They are crushed stones or naturally occurring gravel used in making concrete. Their maximum size can go up to 63mm. Coarse aggregates are usually formed by blasting the stone quarries. Though sometimes, they are also hand-crushed.
Coarse aggregate is a building and construction ingredient made of stones or rocks extracted from ground deposits. Some common ground deposits include crushed stone, river gravel, rock from quarries, and even previously used concrete. It consists mainly of quarry stones, gravel, uncrushed stones, and coarse aggregates greater than five millimeters.
Coarse wash aggregates are available in various sizes that work to fit both the needs of design and specifications set forth by local, state and government operations. Coarse aggregate sizes available through BoDean Co. include the following: 3/4" Wash drain rock ASTM #57 Stone ASTM #8 Stone 5/16 Wash Chip 3/8" Wash Chip Caltrans 1″ by #4
Both coarse aggregates (particle sizes of 20 mm to 4 mm) and fine aggregates (particle sizes less than 4 mm) are required but the proportions of different sizes of coarse aggregate will vary depending on the particular mix required for each individual end use.

According to the source, the coarse aggregate can be described into three categories: Uncrushed Gravel or Stone which is formed from natural disintegration of rocks. Crushed Gravel or Stone that is obtained by crushing of gravel or hard stone. Partially Crushed Gravel or Stone, which is formed by the blending of the above two aggregate.
The aggregates may be dried by heating at 100 oC – 110 o C for not more than 4 hours and cooled to room temperature before testing, if necessary. Sieve the material through 12.5 mm and 10 mm IS sieves. The aggregates passing through a 12.5 mm sieve and retained on a 10.0 mm sieve comprise the test material. Take about 3.25 kg of this material.

Out of all three, aggregate works as a structural filler in the concrete mix. But its role is far more important and essential than that inferred in a simple statement. Coarse aggregate occupies 70% to 80% of the volume of concrete. Aggregates are the material that the cement paste coats and binds together.
Coarse Aggregate Testing Coarse aggregates are used in all fields of construction to produce bituminous mixtures and concrete to be used in structures, fill materials and as base materials in foundations, roads and railways.

Any aggregate particle that retains of sieve #4 is called 'coarse aggregate'. Coarse aggregates (also known as crushed stones) are majorly added in the concrete mix for strength gain purposes. They can be obtained by blasting heavy rock boulders. In Pakistan, we generally use Margalla Crush, Sargodha Crush and Sakhi Sarwar Crush

Aggregates are essential components of concrete. They act as inert material in concrete. Fine aggregate and coarse aggregate are two main types of aggregate for concrete. As the name indicates, they are basically classified depending on the sizes of aggregate particles. Fine Aggregate vs Coarse Aggregate
A crusher with coarse style liners would typically have a 6:1 reduction ratio. Thus, with a 3⁄4" closed side setting, the maximum feed would be 6 x 3⁄4 or 4.5 inches. Reduction ratios of 8:1 may be possible in certain coarse crushing applications. Fine liner configurations typically have reduction ratios of 4:1 to 6:1.
The original rock mined in the form of blasting, etc., is coarsely crushed and finely crushed by a crushing machine, and then divided into finished aggregates of different sizes using a vibrating screen. The types of these aggregates can be distinguished according to the grain size. There are 2 main grain grading sizes.
