Researchers have discovered a remarkably preserved Roman construction site at Pompeii, halted by the 79 AD eruption of Mount Vesuvius. This site offers insights into the ‘self-healing’ properties of Roman concrete, crucial for enduring structures like the Colosseum. The findings reveal the use of a ‘hot mixing’ technique, diverging from earlier theories by Vitruvius, and demonstrate the material’s ability to repair itself through chemical reactions. Professor Masic expressed deep emotional resonance with the well-preserved work area, illustrating the vivid connection to ancient Roman practices.
