Drivers and finishers use it for a load that arrives stiff, warm or close to set: batched with hot materials, held too long on site, overdosed with accelerator, or loaded into a drum that still held returned concrete. A hot load loses slump fast, tempts the crew to add water and leaves cold joints and finishing trouble behind it. Most crews would rather reject it at the chute than fight it on the slab.
That's a hot load, ticket says it was batched two hours ago and you can feel the heat coming off the drum.
