Concrete is a collective name for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Among them, the aggregate composed of sand and stone is the main raw material in concrete, and plays a skeleton and filling role in concrete and mortar. It can be said that gravel aggregate is the basis of concrete production. To develop green concrete vigorously, high-quality sand and gravel are essential.
