In The Pompeii Discovery of Roman Concrete: Revelation of the Self-Healing Secrets that Built an Empire and Challenge Vitruvius offers unprecedented insights into Roman engineering. This book examines archaeological discoveries from Pompeii, where half-built walls, raw materials, and tools preserved in volcanic ash reveal the secrets of Roman concrete. This material enabled the construction of monumental arches, domes, and enduring structures across the empire. Beginning with the history of Roman architectural evolution, the book traces the composition of this self-healing concrete, highlighting key ingredients such as volcanic ash and lime clasts that facilitated chemical reactions that conferred remarkable durability. Excavations conducted from the late 1880s through 2023 have uncovered dry mixtures and structural elements, confirming a "hot-mixing" process that generated heat to embed self-healing minerals, allowing cracks to seal naturally over time. Contrasting these findings with Vitruvius' first-century manuscript De Architectura reveals discrepancies in mixing sequences, suggesting variations in regional practices or interpretations of ancient texts. Comparative analyses from sites such as Privernum extend the discussion to imperial applications, while emphasizing the ingenuity of everyday builders, including enslaved laborers, whose expertise informs icons such as the Pantheon and the Colosseum. The exploration culminates in modern implications, proposing ways ancient techniques could enhance contemporary materials for sustainable infrastructure. Through examination of artifacts and scientific analyses, the book bridges antiquity and innovation, revealing how Roman methods continue to inform engineering challenges today.
