Based on my understanding and please correct me if I’m wrong, self healing concrete isn’t something we’re using today as the method to create it got lost with the fall of the Roman Empire, which is incredibly unfortunate.
A research was posted a few days ago regading this topic. (They figured out the method)
Wow, thank you for posting this. The Romans were ahead of their time and when I read about the self healing concrete, I just couldn’t imagine we haven’t been able to figure out how to do it. Looks like we have!
