Maximum Aggregate Size - CivilWeb Spreadsheets

For concrete pavements the maximum size of coarse aggregate must be small enough to sit suspended within the fresh concrete mix without breaking the surface of the concrete or impeding the compaction of the concrete. For this reason most national standards limit the maximum size of the aggregate to a proportion of the depth of the slab.
