Reminds me somewhat of roman concrete; archeologists were under the impression that roman concrete was poorly mixed due to various hydroreactive additives, that were thought to have been accidentally added during the mixing process.

It turned out these additives grant self healing properties to the structure, as when cracks appear revealing the additives, they expand to fill the crack.

They were surely more advanced than we give them credit for. Unfortunate.
