Roman concrete is like a super-strong glue made from rocks, lime, and volcanic ash. It’s what helped them build amazing structures that still stand today, even underwater! They didn’t have modern tools or chemicals, but their mix was perfect for lasting a long time. It's like using the strongest building blocks you can find to make something really strong.
Examples
- A kid builds a sandcastle with wet sand, the more water it has, the stronger it gets.
- Roman concrete mixed with seawater becomes even stronger over time, like a cookie that gets better when it sits in the oven longer.
