The only "secret" is the random stuff they mixed in concrete for random reasons (blood, urine, ash, flowers etc.) that has no perfomance advantages (except some ashes). Some of their buildings still stand mainly for 2 reasons...

... 1) They were good engineers and they were building for eternity. Today (almost) no one designs buildings for 200/300+ years. We went from an eternal, static view to a evolution/revolution dynamic one. We can do far far better if we wanted, we don't care about eternity anymore

Part of this is they didn't use reinforcing steel and designed for compression without bending stresses. Steel can let water get in We could probably do the same now but it would take relearning And also I'm not modern building codes would allow it but I'm not sure

Not really true. They used unreinforced concrete, which we still know how to do. It lasts longer, but is weaker and less safe. Deliberate tradeoff we're making; meanwhile, they couldn't have built the steel-reinforced concrete we use.

Think of what it was like after the fall of Rome as medieval people gazed at Roman ruins of baths with piping & hot water systems not knowing how the Gods could have built such things. For centuries after the fall of Rome, soap became unknown. Civilization often goes in reverse.

Is it possible that in the case of their uber concrete for example, they weren’t necessarily more technologically advanced but instead just happened to be in direct contact with raw materials that coincidentally were the perfect recipe for this?

Their aqueducts are a counter example to this but still
