It’s concrete, not cement. (Sidewalks for example, or foundations of buildings, etc)
Cement is an ingredient in concrete.
I didn't know you were on Lemmy, dad!
Rofl. My dad is WHY I do this.
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
Are you my brother-in-law?
Serious question, but is a cement mixer actually full of concrete and not cement then?
Initially, no.
But once they put stuff in it, displacing the air it's initially filled with, that stuff is indeed concrete (aggregate + cement + water), not just cement.
Compromise and call it clinker?
