Why Roman concrete is still stronger than RAAC (and other modern concretes) (www.chemistryworld.com)

The concrete dome of the Pantheon in Rome remains stable enough for visitors to walk beneath, and some Roman harbours have underwater concrete elements that have not been repaired for two millennia – even though they are in regions often shaken by earthquakes.

Whence this remarkable resilience of Roman concrete architecture? It’s all down to the chemistry.

We build for decades, literally ALL of our materials are better. We know why we make things the way we do and we choose according to the thing we are building. Now, I think we are doing some practice with concrete because it's the most used thing in the world, it's even a strong co2 contributor. There is no mystery about the concrete, no conspiracy, there is nothing but the fantasy being peddled by people who need to find fisting in their lives so it can fill that emptiness

Well if some research on Roman concrete can help us better understand self healing, won't that be good?

We already know how it works and it doesn't work for modern uses of concrete. Of course it's good to know, but it's been some years now that people keep talking about roman concrete as if it's adamantium or something
