Aggregates
Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar. Those particles that are predominantly retained on the 4.75 mm (No. 4) sieve, are called coarse aggregates. …

How Fine Aggregate Affects Mix Design of Concrete?
Fine aggregate is on of the major constituents of concrete which can influence concrete mix design substantially.

The Effect of Aggregate Properties on Concrete
Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate.

Aggregates | Difference Between Coarse And Fine
With most particles going through a 3/8-inch sieve, fine aggregates typically consist of natural sand or crushed stone.. All particles larger than 0.19 inches are coarse aggregates but usually vary between 3/8 and 1.5 inches in diameter.Gravels make up much of the remaining coarse aggregate used in concrete with crushed stone.. Natural …

Fine Aggregate is smaller in size. Coarse Aggregate is bigger in size. Fine Aggregates are passes through a 4.75 mm sieve and retain on a 0.075 mm sieve. Coarse …
How to Choose Quality Coarse Aggregate for Concrete Construction?
Coarse aggregate should contain various fraction sizes to ensure adequate compaction of particles, hence resulting in increased density and reduced voids in concrete. In the majority of concrete works, aggregate sizes of 20 mm or smaller are used. To ensure good coarse aggregate compaction and higher concrete density, it is recommended to mix ...
Difference Between Fine and Coarse Aggregate
The voids between the coarse aggregate are filled up by fine aggregate. Coarse aggregate acts as inert filler material for concrete. 7: Uses: Fine aggregates are used in mortar, plaster, concrete, filling of road pavement layers, etc. Coarse aggregates are mainly used in concrete, railway track ballast, etc.
How Coarse Aggregate Affects Mix Design of Concrete?
Coarse aggregate is one of the essential components of concrete and occupies the largest volume in the mix. That is why it greatly affects the concrete mix design. Its properties such as strength, maximum size, shape, and water absorption influence water demand, the quantity of cement and fine aggregate in concrete mixture.
