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.
