Aggregates comprise 60 to 75 percent of the total volume of concrete. The type and size of aggregate used depends on the thickness and purpose of the final concrete product. Relatively thin building sections call for small coarse aggregate, though aggregates up to six inches in diameter have been used in large dams.
