The term aggregate can be defined as a piece of mineral or recycled rock, measuring up to 125 mm, which is mainly used in the field of construction for building works (concrete, buildings, bridges) and civil engineering (roads, highways, railways).
These aggregates come from quarrying and sand pits (loose rock, solid rock) but also through marine extraction by dredging. As environmental standards become increasingly stringent, the development of aggregate recycling, resulting from mobile sites or the recovery of industrial products such as clinker, is growing and will certainly gain prominence over the coming years.
