About this book:

**The Roman Empire didn’t just conquer the world with legions—it built it with a recipe that defies time itself.** The Pantheon’s dome still stands, the Colosseum endures, and ancient harbors remain intact under seawater that corrodes modern concrete in decades. The secret? A lost science of volcanic ash, self-healing chemistry, and engineering genius that even today’s materials scientists are struggling to replicate. *The Hidden History of Roman Concrete* takes you deep into the mystery of how Rome built for eternity—and why that knowledge vanished.

**This isn’t just a history lesson—it’s a blueprint for the future.** From the pozzolana quarries that fueled an empire to the cutting-edge labs now mimicking Roman self-healing concrete, this book bridges ancient wisdom and modern innovation. Discover how the Romans created structures that repair themselves, mastered hydraulic formulas for underwater construction, and practised sustainable building that rivals today’s green standards. You’ll never look at a crumbling ruin the same way again.

**Packed with twenty-five chapters that decode Vitruvius’s recipes, explore the chemistry of durability, and even ask what Roman concrete could teach us about building on Mars, this is the definitive guide to the most resilient building material ever invented.** Whether you’re an engineer, a history buff, or just someone who’s ever wondered why the Colosseum is still standing while our own bridges fall apart, this book will change how you see the past—and the future.
