The secret of Roman concrete found.

Details [url=bigthink.com/paul-ratner/why-ancient-roman-concrete-lasts-for-millenia-but-ours-crumbles-in-decades]here[/url].

Romans created concrete by mixing volcanic ash, quicklime and chunks of volcanic rock. Even though they figured out the ingredients, scientists still didn’t know the recipe. How did the Romans manage to make the concrete so long-lasting? The key turned out to be in the chemical reaction caused by the addition of seawater.

The Roman concrete was made to interact with its environment, as opposed to modern concrete which stays inert and gets damaged over time. Seawater is the reason why the mixture gets stronger. As seawater reacts with volcanic material, new minerals are created that reinforce the concrete.

Very cool. Our forebears were some pretty smart cookies.

Discordia is obviously the answer.
