4 Different Types of Aggregates Everyone Should Know
Sand is a very fine aggregate that can be both naturally occurring and manufactured. The use of sand is very common within construction as it provides strength and stability to materials such as concrete, cement and asphalt. It is also used as a base layer to provide a clean and level surface. Sand is a much finer product than gravel.
