Specification of Coarse Aggregate

Coarse Aggregate Coarse Aggregate consists of natural occurring stones (crushed, uncrushed or broken). It should be hard, strong, dense, durable, and clean. It must be free from veins, adherent coatings and injurious amounts of disintegrated pieces, alkali, vegetable matter and other deleterious substances. It should be roughly cubical in shape.

What is Aggregates

Aggregate Classification | Types of Aggregates. Aggregates are variously classified on the basis of their grain size, their origin, and their volume-weight as follows: (1.) 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.
