### Gradation Of Aggregates Types of Aggregate

2019-10-5 Gradation of Aggregates Definition. The particle size distribution of an aggregate as determined by sieve analysis is termed as gradation of aggregates. If all the particles of an aggregate are of uniform size, the compacted mass will contain more voids whereas aggregate comprising particles of various sizes will give a mass with lesser voids.The particle size distribution of a mass of aggregate
