Aggregate Sizing Explained

Jan 15, 2016· Aggregate serves as a reinforcement to add strength to composite materials such as concrete Aggregates can be categorized into three groups: fine aggregate, coarse aggregate, or all-in aggregate Fine aggregate, such as concrete or masonry sand is defined as material that mostly passes through a 475 mm IS sieve.

What is the size of coarse aggregate used in concrete?

When the size of aggregate is greater than 475 mm ( say 5 mm) it is called coarse aggregate Graded aggregates are used for better particle packing The larger the size of aggregate lesser the cement required for same strength up to certain grade.

Coarse Aggregates Fine 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 475 mm (No 4) sieve, are called coarse aggregat.

Function and Importance of Aggregate in Concrete

Nov 21, 2016· • Coarse aggregate is used to describe particles larger than 475 mm, and the term fine aggregate is used for particles smaller than 475mm; typically, fine aggregates contain particles in the size range 75 µm to 475 mm, and coarse aggregates from 475 to about 50 mm, except for mass concrete which may contain particles up to 150 mm.
