Yes, that's what I had hoped the larger one would model, the look of cement/concrete. It is a piece of a cardboard tube around which a roll of carpeting had been wrapped. It cut neatly with a small hacksaw so my imagination was piqued and I tried my best using it.
The smaller tube is a piece of plastic tubing, perhaps as wide in diameter as a quarter, also trying to be cement/concrete-looking.
Both got painted with a cement/concrete-colored acrylic. by dabbing the color on, not brushing.

P.S. And Mark, given Paul's suggestion to you, above, about considering modeling a concrete culvert, perhaps, these photos may offer you a reference point, too?
