Roman concrete is unreinforced, meaning no rebar inside to rust. You can't use modern construction techniques with unreinforced concrete. It can't handle tension well.

Seriously, there's a reason we don't "build like the Romans". We would be using 10x the concrete that we use now. We can't even keep up with concrete demand now, I can't even imagine how much worse the environment would already be if we needed 10x the concrete.

If we needed 10x the concrete, we wouldn't have built so many cheap ugly concrete buildings.
