What Is Fine Aggregate? Fine aggregates are essentially any natural sand particles won from the land through the mining process. Fine aggregates consist of natural sand or any crushed stone particles that are ¼" or smaller. This product is often referred to as 1/4''" minus as it refers to the size, or grading, of this particular aggregate.

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.

The workability of fresh concrete were ...
5. Size and Shape. The size of aggregates less than 4.75mm is called fine aggregate and beyond 4.75mm is called coarse aggregates. The size and shape of the aggregates impact the strength and durability of the concrete. The workability of concrete might be affected when using large size aggregates.
· Fine aggregates provide dimensional stability to the mixture. The elastic modulus and abrasion resistance of the concrete can be influenced with fine aggregate. Fine aggregates quality also influence the mixture proportions and hardening properties.
· Fine aggregates have 100% of their material passing the 10 mm sieve. Coarse aggregates have the bulk of the material retained on 4.75 mm sieve. Aggregates comprise the greatest volume percentage in portland-cement concrete, mortar, or asphaltic concrete.
3 Physical and Chemical Properties of Aggregate. The physical properties of aggregates stem from the inherent properties of the source rock; these include texture, structure, and mineral composition. Textural properties give rise to internal characteristics, of which the pore size is perhaps most important. Structural characteristics define the ...
