Title says it all; I’m sure a thin layer of cement will be left over after they poor it all, and I would imagine that thin layer would harden and then the next time they use the mixer another thin layer would be leftover and so on and so forth. After a while I would imagine it would accumulate to the point where it renders the mixer unusable.
Why is this not the case?

I have zero authority on the matter, but I was told that concrete trucks have a barrel of reserve water so that if you hit the time limit the driver can dump the water in. It ruins the batch of concrete but saves the truck.
I also once met a financial planner from the mid West. He built his whole practice on concrete companies….they can only be a max of 45 min drive from each other. He set up and run all their retirement plans. Genius!
