3. The advantage of small aggregate in the water-ratio strength relationship may or may not be sufficient to offset the effects of its higher mixing water demand. It appears that optimum maximum size, so far as strength is concerned, will vary for different aggregates, different cement factors, different test ages and probably other conditions. 4.

Maximum Aggregate Size - CivilWeb Spreadsheets

Firstly the definition of maximum aggregate size in concrete is the smallest sieve through which 100% of the aggregates will pass. The nominal size of aggregate is the smallest sieve which can retain more than 15% of the total aggregates, though this is sometimes taken as the next sieve size down from the maximum aggregate size.
