Coarse aggregate (stone) The aggregate with particle size between 4.75 mm and 9.0mm is coarse aggregate, commonly known as the stone. It can be divided into two types, that is, gravel and pebble. Gravel is natural rock or rock by mechanical crushing, screening system, and the particle size is larger than 4.75 mm of rock particles.
