Yes, everything is over-engineered with belt and braces x2 when it comes to reinforcement, just during my active years in the construction industry, the reinforcement has noticeably increased.

The Romans invented self-healing concrete, 2000 years ago.
However, I have no knowledge if this prevents the reinforcement from rusting.
Should, in a way, make the concrete less porous, more resistant to moisture penetration.

They were even smarter when they invented a climate without freeze-thaw damage and all the things that didn't turn out well, the evidence has disappeared for

The Romans invented self-healing concrete 2000 years ago.
However, I have no knowledge if this prevents the rebar from rusting.
It should, in that case, make the concrete less porous, more resistant to moisture penetration.

But porous concrete sounds like it can absorb more moisture and that is bad for the rebar used.
Then I feel that concrete has changed for the worse through my years in the industry and it is the environmental requirements on the material and manufacturing..
