Ancient Roman concrete is super strong and lasts for hundreds of years because it has a special recipe that makes it tough and flexible, like a well-made playhouse.
How It Was Made
Roman builders used a mix of limestone, volcanic ash, and seawater. This made the concrete really hard, but also gave it the ability to heal itself when it cracked, kind of like how your skin heals after a little scrape.
Why It Lasts So Long
When rain or seawater gets into cracks in the concrete, something cool happens: new minerals grow inside the cracks and fill them up. This is like when you put a band-aid on a cut, it helps keep the wound closed and strong again.
Because of this special mix and healing power, Roman buildings like baths, bridges, and even underwater walls have lasted for thousands of years, some still look as good today as they did back then!
