Vent: watched a guy finish a 12x20 slab in Amarillo last Thursday and he never once checked the slump
He kept adding water right out of the hose because the mix looked 'stiff' to him, and by the time they started floating, the surface was already bleeding so bad you could see standing water in the low spots, so I gotta ask, how many of you actually keep a slump cone on the truck or do you just eyeball it like this guy?
