    Aggregates for Concrete Greenspec

    - Fine aggregates are usually sand or crushed stone that are less than 9.55mm 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. 20 mm aggregate . Common aggregates .
