Difference Between Fine and Coarse Aggregate - …
Fine Aggregate vs Coarse Aggregate. Fine and coarse aggregates have some major differences. Sources of main differences between deep and shallow footings are definition, size of particles, materials, sources, surface area, function in concrete, uses, etc. In the following table the main differences between Fine and coarse aggregate are given:

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.
