Let's take a closer look at the materials that go into making concrete. We're talking about cement and aggregate, both of which are usually sourced from quarries and mines because they come in powdered form you can't find anywhere else. All said, those start out costing more than $80 per ton of aggregate or cement. The next step should be obvious; transporting these items to factories where they'll be processed for construction purposes will cost thousands of dollars each day (airlines charge heavily for fuel but those shipping companies don't). After all this transportation has been paid for, there's the laborer who must make sure to follow safety regulations during any manufacturing process so things like mesothelioma doesn't become an issue.
