Im trying to remove some carriage bolts that were used to secure the base of a temporary wall into a concrete slab. Whats the best way to remove them?

There may be a nut down there and you can unscrew it but if they just
bent the end of the bolt, welded it to rebar or whatever, you are
chipping it out or cutting it off.

Doesn't it have a square section just below the round head?

No. I would guess (it's been a while) a 3 pound hammer, 1/2 to 5/8 inch bolts.

You'd be surprised how brittle they are. Hit them fairly hard and they snap instead of bending. Never had to grind one down like you would if you used a cutoff saw.
