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.

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.
