>> (then stain it) to possibly look similar to those awesome cement floors??
Sorry, not that I know of! I meant just to knock off the high spots and smooth them a little, so that paint (or the primer coat) goes farther and produces a smoother painted finish without having to apply as many coats.
(P.S. Someone once posted that they had painted cinder blocks using a roller and household latex paint (thinned with water for some reason). It took a few coats because the cinder blocks sucked up the first coat really fast. But even a few coats gave her the color she wanted (sand).)
I never thought of
staining it to try to preserve the "pebbled" surface. With what, urethane? Hmmm! I have seen marble floors where the marble had tiny spiral shells embedded in it (fossils?). That would really be a Neo-Neolithic look!
>> Can my DH use his "Uhhhgh! Unnngh! Unnngh-grinder/sander" and get dirty with it??
Certainly! I hadn't thought of a power tool. It was the "banging rocks together" aspect that appealed to my Inner Cave Man, or at least rubbing them against each other to get a smoother surface. It would chew up less sandpaper if the first pass was cinder-block-against-cinder-block.
One definition of Neolithic vs. Paleolithic is that the New Stone Age has
polished stone tools made sharper and smoother by
grinding. So that is
really getting in touch with our ancient DIY ancestry.

Now that I think about it, sure a belt sander is just like grinding rocks together! High tech rocks! If we could bring belt sanders back into pre-history (along with generators), they might worship us as DIY gods!
Uhhhgh! Unnngh! Ugga-Unnngh!!
This is my Stonehenge-in-the-Seniors'-Park-look:
