Can cardboard absorb cement? If not, other suggestions for a load of toilet-paper-tubes please!

Brought up on a diet of MacGyver and Blue Peter, I have somehow managed to amass a large number of the cardboard tubes from inside toilet and kitchen paper rolls. I think I had the idea of making a sort of honeycomb shelf out of them, but I would like to spray or dip them in concrete for aesthetic and stability reasons.
As best I can tell, cardboard is often suggested as a mould for cement, which suggests it doesn't absorb it. How can I go about this?
Other suggestions on what to do with about 200 bogroll inserts gladly accepted, but something that requires loads of them rather than individual ideas (like dog-treat-makers, or potting solutions).
