Introduction to Concrete
The maximum size of coarse aggregate is typically 19 mm or 25 mm (3/4 in. or 1 in.). An intermediate-sized aggregate, around 9.5 mm (3/8 in.), is sometimes added to improve the overall aggregate gradation. Since aggregates make up about 60% to 75% of the total volume of concrete, their selection is important.
