I was watching a concrete delivery yesterday and got to wondering -

what happens with the concrete that is left over in the truck? I

suppose they keep the truck turning with some extra water so it

doesn't solidify into a solid block, but then what? Does it get used

for something, or do they just have to find a place to dump it?

I could use it where can i contact someone for the cement?
They often pour big concrete blocks with the leftovers that are used
as "guard blocks" at onstruction sites etc.
