Vent: poured a 24x30 slab in Yakima and the mix came in 1.5 inches slump, had to scramble
Told the driver to add water at the chute and he fought me on it, so I killed the pour and called the plant for a new truck. Cost me 3 hours and the homeowner watched the whole thing, so what do you all do when a load shows up that stiff?
