I have a problem with people using the word cement when they mean concrete; they are not interchangeable, yet people write and say it all the time. To clarify, cement is the powder used to make concrete. The hardened surfaces on which we walk and drive are concrete, not cement. Its really no big deal, just something that leaps out at me when I read it or hear it.
Given a choice, I’d much rather land on a pile of cement than concrete.
or using either one when they mean asphalt.
