Classification of Aggregates Based on Size Aggregates are available in nature in different sizes. The size of aggregate used may be related to the mix proportions, type of work etc. the size distribution of aggregates is called grading of aggregates.

There is strong evidence that aggregate type is a factor in the strength of concrete. Ezeldin and Aitcin (1991) compared concretes with the same mix proportions containing four different coarse aggregate types. They concluded that, in high-strength concretes,
doubt that a solid piece of stone, of certain volume, will weigh more than an equal volume of sand crushed from the same material. The volume of this interparticle void space in an aggregate may be measured by the standard method of test for voids in aggregate for concrete (ASTM Designation C30), and this test, used in conjunction with
1 tonne or 1000kg of MOT type 1 stone aggregate will cover approximately 10 square meters to a depth of 2 inch (50mm) after stone has been compacted using a vibrating roller or compactor plate.
