Aggregate is a granular material obtained by processing natural materials. BS882 splits aggregate into coarse and fine elements, coarse being described as gravel or crushed rock and fine being described as consists of particles of a rock, of a controlled particle size distribution, used in the construction of a building or civil engineering structure.
