### Aggregate Sizing Explained - Chaney Enterprises

Jan 15, 2016· There are seven standard sieves for fine aggregates ranging from No. 100 to 3/8” and 13 standard sieves for coarse aggregate ranging from No. 16 to 4”. For example coarse aggregate has a standard grading requirement for each different size from #1 to #8. A #1 aggregate is a nominal size of 3 ½ to 1 ½ inches and a #8 aggregateDifferent Types & Sizes of Aggregate for Concrete,,Aug 11, 2018· [2] COARSE AGGREGATE. 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.Aggregates for concrete | Aggregates sizes for concrete,Apr 06, 2020· Fine aggregates; Coarse aggregates; 1) Fine aggregates:-The aggregates whose size is less than 4.75 mm are known as fine aggregates. Fine aggregate is also known as sand. 2) Coarse aggregate:- The aggregate whose size is greater than 4.75 mm is known as coarse aggregate. Stone is also known as coarse aggregate.

### What nominal maximum sizes of aggregate are recommended?

Because maximum aggregate size can impact concrete properties such as shrinkage, and also the cost of concrete, the largest aggregate size consistent with the requirements of 26.4.2.1 should be permitted. With the w/cm fixed, the larger the nominal maximum size of aggregates, the lower the cement content for a given consistency.
