Aggregates are coarse particulate rock-like material consisting of a collection of particles ranging in size from < 0.1 mm to > 50 mm. It includes gravel, crushed rock, sand, recycled concrete, slag, and synthetic aggregate. 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.

Aggregate definition and Shape, Types, Properties Aggregate definition. Aggregates are the major ingredients of concrete. Aggregates are derived from rocks. They are broadly divided into two categories i.e. fine aggregate and coarse aggregate. Their properties are depended on the mineralogical composition of the rock. Crushed rocks are used as coarse aggregates are river sand is used as fine aggregates.

types of coarse aggregate definition chemistry
Coarse aggregate is used to describe particles larger than 4.75 mm, and the term fine aggregate is used for particles smaller than 4.75mm. Fine aggregates contain particles in the size range 75 µm to 4.75 mm, and coarse aggregates from 4.75 to about 40 mm, except for mass concrete which may contain particles up to 150 mm.
Aggregate Concrete - an overview | ScienceDirect Topics
The objective of any concrete aggregate processing operation should be the production of good-quality, 'clean' coarse and fine materials in the normal range of sizes. The types of equipment used and the flow design of the plant are more or less completely dependent upon the nature and properties of the source raw material.

In grading of aggregates, the voids in the mixed aggregate would be minimum when the sand is just sufficient to fill the voids in the coarse aggregate. Voids in the coarse aggregate are filled in by sand and voids in the sand are filled in by cement. Mix that occupies the least volume is the densest and will produce the best results.
