The issue isn’t concrete or cement inherently but how much of is used. And it’s used because it’s either the most cost-effective material or just the only one able to deliver the required specs.
I thought the issue was sand/silica and the fact that we may exhaust the ressources to do cement eventually. It takes a lot of sand materials if I recall correctly ?

Except it isn’t just about the energy intensity, but specifically the CO2 emission from the concrete process itself.
