Won't that risk corroding the copper pipes?

Any more so than, say having a copper pipe outside, exposed to the
elements? If so, I suppose the pipes could be painted first, to protect
them from whatever corrosives might be present in concrete...

Actually, from what I have read, I think it entirely possible that
concrete/cement could be far more aggressive than "weather".
