Classification Of Aggregate Based On Size Shape Unit Weight

Classification Of Aggregate Aggregate classification. The classification of Aggregate is generally based on their geological origin, size, shape, unit, weight, etc. Aggregate is the major ingredient of concrete. Aggregate is derived from rocks. They are broadly divided into two categories i.e. fine and coarse aggregates.

Classification Of Aggregates According To Nature Of

Aggregates play the major role to make the main matrix of the concrete. It is a collective term for sand, gravel and crushed stone. It is used with a binding medium such as cement, lime, etc. to form a solid mass of concrete.. Also Read Know the Role of Aggregates in Concrete According to the size, the classification of aggregates is fine aggregates and coarse aggregates.
