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.

This article is literally about doing research to better understand the chemistry behind the self healing properties of Roman concrete to maybe use the findings to improve modern concrete. This is the aspect which I find so interesting : the chemistry. Literally no one is talking about going back to traditional values and blah blah. That's something which I personally abhor. Did you even read the article? Where did you find this in the article? Of course titles of articles tend to be over dramatic.

We know about thw chemistry and we know it's not compatible with rebar. So it's just a bunch of wank, ooh the good old times etc
