Maximum Aggregate Size - CivilWeb Spreadsheets

BS EN 13877-1 limits the maximum aggregate size in concrete to one third of the spacing between reinforcing bars. This is a more onerous restriction than in US standards which specify a maximum aggregate size of ¾ of the minimum spacing.

Maximum Aggregate Size Information - concrete.nist.gov

2000-12-7  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.

What nominal maximum sizes of aggregate are

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.
