Aggregate Sizing Explained. Fine aggregate, such as concrete or masonry sand is defined as material that mostly passes through a mm IS sieve. This is then broken down into four types of grading Zones 1 through Zone 4 with Zone 4 being the most fine. Coarse aggregate can be described as uncrushed, crushed, or partially crushed gravel or stone.
The maximum size of aggregates generally used in concrete can be as large as possible within the specified limit.
