Solidified ruined company with red cent (9)

'solidified' is the definition.
(concreting is a kind of solidifying)

'ruined company with red cent' is the wordplay.
I cannot really understand how this works, but
'company' could be 'co' (abbreviation) and 'co' is located in the answer.
'red' could be 'r' (I've seen this in other clues) and 'r' is present in the answer.
an anagram of 'cent' is 'ncet' which is present in the left over letters.
The remaining letters 'ed' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
