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. Or, stated

Maximum Aggregate Size Information

In general, smaller size aggregates have been shown to produce higher strength concretes, for a fixed w/(c+p) ratio. However, the use of the largest possible coarse aggregate may be an important consideration in terms of optimizing modulus of elasticity, creep, and drying shrinkage of the concrete.

Single-size aggregate is based on a nominal size specification. It contains about 85 to 100 percent of the material which passes through that specified size of the sieve and zero to 25% of which is retained in the next lower sieve. A graded aggregate contains more than one single-size aggregate.
