It's "cement concrete," or in other words, concrete with a cementitious binder (e.g. lime, Portland cement, pozzolan, fly ash, etc.).
That's in contrast to "asphalt concrete" (the black stuff roads are often paved with), which is concrete with a heavy petroleum (asphalt, a.k.a. bitumen) binder.
"Concrete" just means aggregate plus a fluid binder that cures and hardens. Arguably, things like epoxy quartz countertops and terrazzo flooring are "concrete," too.
quite a concrete answer
Really cements my understanding of the topic.
I can't find asphalt with his explanation either!
Fair point. I usually just correct people when they are talking about cement concrete. I’ve never actually heard of “asphalt concrete”
I just inherited this quirk from my dad is all
That's normal; it's the kind of minutae you learn while getting a civil engineering degree.
I hope the next time your father uses asphalt you correct him
