Scientists just found a construction site in Pompeii that’s basically a time capsule—and it’s blowing up what we thought we knew about Roman concrete. Turns out, Romans used a “hot mixing” technique with quicklime that made their concrete self-healing (yes, it literally fixes its own cracks). This stuff helped them build epic stadiums and harbors that still stand today. Modern builders are taking notes—could our future buildings last thousands of years too? #History #Pompeii #RomanConcrete
