Shape, Size Coarse Aggregates

Coarse aggregates are classified into two main groups: (i) single-size aggregate and (ii) graded aggregate. Single-size aggregate is based on a nominal size specification. It contains about 85 to 100 percent of the material which passes through that specified size of the sieve and zero to 25% of which is retained in the next lower sieve.
