Jun 30, 2021Typically, 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. Larger aggregate sizes use less cement and water.
