Thanks for that. Just reading this article/explainer:

Hospitals, courts and a shopping centre (mall): Which other buildings are at risk of concrete collapse?

They're slowly doing assessments and it does seem really bad to me

Thanks for the link, what a MESS! The thing about water reaching rebar is that it will wick-along the rebar and damage a good length of it, even if only its end is exposed. It’s CRAZY to use a porous concrete with rebar!

By the way, the Roman Pantheon is nearly 2000 years old and was made with concrete that actually self-heals and no rebar (but then it starts at 6 feet thick). We’re still trying to figure out the recipe for their concrete!
