If the slump is around this range it will be too much tight & not flow able specially in case of ares if more steel (Main & Extra Steel), I See that the slump start from 75 mm to 125 mm, However this mentioned slump from 50 mm to 10 mm is recommended for Gunite Concrete.

For slabs and beams, it should be 30 to 125.
For columns 75 to 125.
For foundation, it should be 50 to 100.

Reinforced foundation, footings, and walls -> 50-100.mm.
Reinforced slabs and beams -> 30-125.mm.
Columns -> 75-125.mm.

Pavements -> 25-50.mm.
Mass concrete structure -> 25-50.
Unreinforced footings -> 25-75.
Bridge decks -> 25-75.mm.
