Well Graded Concrete Aggregate Over the years, I have wondered why the ASTM specifications for concrete aggregate have a gap in the aggregate grading between the ⅜” size to the 7 mesh. Back in April 2012, I was visiting with Richard Szecsy about becoming a member of the Texas Aggregate and Concrete Association.

The usual range is between 9.5mm and 37.5mm in diameter. 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 common in mass concrete. Larger aggregate diameters reduce the quantity of cement and water needed.
