How a 1 900 year old latrine helps explain why roman concrete lasts?

A 1,900-year-old latrine shows us how Roman concrete stays strong for so long, it's like a super-strong cookie that doesn’t crumble even after eating snacks every day.

Roman concrete was made with limestone, volcanic ash, and lime, kind of like mixing different kinds of flour to make the best bread. When this mix got wet, something special happened: it started to harden really well, even in water.

Imagine a bathroom that people used for centuries. That’s what the latrine was, like an ancient public toilet. Over time, all the pee and poop made the concrete get wet and messy. But instead of breaking down, it got stronger! It's like if your cookie became tougher after getting splashed with juice, it didn’t fall apart; it stood up to the mess.

It’s like having a backpack that gets heavier but doesn't tear, it just gets better at carrying stuff!
