Aggregates: Meaning and Classification | Materials ...

The strength of a fully compacted concrete with a given water/cement ratio is independent of the grading of the aggregate. Grading only affects the workability of the mix and the development of strength corresponding to a given water/cement ratio requires full compaction, which can be achieved only with the sufficiently workable mix.
