Question
How does the increase of maximum aggregate size used in the concrete mix design affect the percentage of fine aggregates needed for the mix? Explain why this is the case.
Expert Solution
Reason

For well-graded aggregates, the voids should be filled by fine aggregate particles for a rigid and high compaction.
We need more fine particles for better interlocking.
