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
When we call a concrete truck on a construction site we always need to keep a space for the truck to dump any residue of concrete left and to wash. Each truck have a tank of water to wash on the site. You can see an example of this [here](https://www.youtube.com/shorts/dDZrp11yopw).
Obviously this isn’t perfect, but it get the job done in-between site. At the end of the day, the truck will do a more thorough clean like seen [here](https://www.youtube.com/watch?v=_nzsTKQBUAc).
