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.

A Detailed Guide on Grading of Aggregates.Grading of Aggregates. Grading of aggregates is determining the average grain size of the aggregates before they are used in construction. This is applied to both coarse and fine aggregates.The aggregate sample is sieved through a set of sieves and weights retained on each sieve in percentage terms are summed up.
