Aug 11, 2018 Coarse aggregates are particulates that are greater than 9.5mm. The usual range employed is between 9.5mm and 37.5mm in diameter. Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete. Larger aggregate diameters reduce the quantity of cement and water needed because of its
