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?
In: Engineering
It can. There are known cases of it not getting used fast enough and curing in the barrel. This can cause the entire barrel to become a loss and need replacement.
But concrete companies and drivers know about this and are usually smart enough to know when the load needs dumping. It’s the dummy drivers who end up ruining their trucks by allowing the curing to occur.
