All About Coarse Aggregate: Types & Properties
The coarse aggregate used in making concrete contains aggregates of different sizes. This particle size distribution of the aggregate is termed "Gradation". The sieve analysis was conducted to determine this particle size distribution.

Coarse aggregates usually form the stone skeleton. Fine aggregates fill the voids of the coarse aggregate skeleton and asphaltic mastic that consists of bitumen, and the filler acts as the binder phase to bond all of the aggregates together as a whole. In such a structure, the coarse aggregate skeleton is the main load-carrying part and thus …

3. Shape of Coarse Aggregate. Coarse aggregates may be round, angular, or irregular shape. Rounded aggregates have lowest water demand due to lower surface area, and also have lowest mortar paste requirement. These properties make rounded aggregate to yield the most economical mixes for concrete grades up to M35.
