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?

Around here every cement truck driver has a brother in law who has a
driveway formed up on the sides only. Left over cement is dumped off
at BILs trailer house on the way back to the plant. Also looks like to
stop this practice the plants load every load short about 1/2 yard but
in reality it forces a truck to go back for another load, at the
customer's expense
