How are Aggregates Classified? | General Kinematics


Size is one of the most important parts of classifying an aggregate. Typically, the size of the aggregate is divided between fine and coarse selections. Fine aggregate like sand is used to fill in the void created when coarse aggregates are combined. Fine aggregate is also used to fill in sand traps on golf courses.

Typically, coarse aggregate sizes are larger than 4.75 mm (5 mm in British code), while fine aggregates form the portion below 4.75 mm. A maximum size up to 40 mm is used for coarse aggregate in most structural applications, while for mass concreting purposes such as dams, sizes up to 150 mm may be used. Fine aggregates, on the other hand, have particles up to a minimum size of 0.075 mm ...

Aggregate Types on the basis of Grain Size. This is the most common classification, where in two types of aggregates are distinguished: (Fine and Coarse). (i) Fine Aggregates. In the Fine Aggregates, the grain-size lies between 4.75 mm and 0.15 mm. In other words, these pass-through from sieve with the mesh size of 4.75 mm and are retained on a sieve of 0.15 mesh size. Sand is the most ...
