Concrete Q & A: Maximum Size versus Nominal Maximum Size ...

Maximum Size versus Nominal Maximum Size: The specification I prepared for a project calls for “Maximum coarse aggregate size to be 1 in. nominal.” I intended this provision to mean that almost all of the coarse aggregate used in the concrete would pass the 1 in. (25.0 mm) sieve and some would be retained on the 3/4 in. (19.0 mm) sieve ...

Practical Grading of Aggregates | Concrete Technology

Zone II represents medium sand, generally suitable for the standard 1:2 fine to coarse mix, when the maximum size of coarse aggregate is 20 mm. The choice of correct proportion is particularly important as the grading of the sand approaches the fine outer limit of zone 4 or the coarse outer limit of zone I.
