 · Construction aggregate, or simply aggregate, is a broad category of coarse to medium-grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete, and geosynthetic aggregates. Aggregates are the most mined materials in the world. One of the essential types of construction materials. 11. Bricks

 · Coarse aggregates are particles larger than 4.75mm in diameter. Typically, a diameter range of 9.5mm to 37.5mm is used. Fine aggregates are often sand or crushed stone with a diameter of less than 9.55mm. The most often utilized aggregate size in construction is typically 20mm. In mass concrete, a greater size, 40mm, is more frequent.
