One reason is the demand. A retailer told me several yr.s ago he was
having problems getting cement. Concrete is rock, sand & cement. The
Chinese were buying literally billions of yards of cement. The Dams in
their 7 Gorges project was gg to require billions & billions of yards
of concrete. Recently a TV program abt. the 7 Gorges project said China
has moved over 1 million people from where the dams are going. Imagine
moving a large city to build something.
Here concrete redi-mix vendors are using a 4 yard minimum delivery
charge. You use one or two yards for a base you still pay for 4 yards
even if they take the leftover. Most vendors charge a fee for 'waiting
time' if you can't get the concrete off the truck in their allotted
time. Most charge so much a minute after your time expires!
I just poured 1 yard for a base using the 60 lb. bags you get at the big
box store. Way cheaper if you can do the work yourself. My Dad delivered
redi-mix for over 25 yr.s so I know a few things to make pouring easier.
If you're not knowledgeable abt. concrete ask someone who knows. You do
a bad pour & you can't just shovel it out & start again. Once it 'sets'
it's there. Period.
