FYI. If you're talking about the stuff in the big round trucks that final product is concrete. Cement is an ingredient in concrete, a chemical binder.
Normally for "sidewalk concrete" that binder is an ingredient called "Portland cement", and the final product is "Portland cement concrete" or P.C.C. Probably the stuff your friend is working with.
For road paving, often referred to as black-top, the binder is Asphalt, and that is called "Asphaltic Concrete," or A.C.
And of course these terms might be local as well, this is what we call them in Southern California.
But the fact that the smaller company doesn't computer control and errs on the side of caution is a great illustration of the difficulty of working in this space. And that 10 miles can make a difference. I believe it!
For large road projects in the boonies they typically have to build concrete mixing plants on site! The look like a collection of huge round tank-style trailers tilted upright and assembled all together.
Edit - spelling.
