– How does leftover cement in cement trucks not harden and slowly accumulate in the mixer, essentially clogging it?

1.40K viewsEngineeringOther

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?

Go to a new home job site after a slab is poured. You’ll find patties of cured concrete all around. They also have on board hoses and water supply to keep everything washed out
