Classification Of Aggregates Used In Construction Work ...

Jul 29, 2020· A single size aggregate in an aggregate when most of the quantities are of the same size is called a single size aggregate. Particles of many other sizes are absent in such aggregates. E.g. A single size aggregate of 20 mm means that most of the aggregate passes through the 20 mm IS sieve and most of the volume stays on the 10 mm IS sieve.
