Roman concrete
Pantheon's building material
Roman concrete is theite building material used by ancient Romans, made from volcanic ash, lime, and seawater.
Unlike modern Portland cement, it actually strengthened over time—Roman harbor structures have endured two thousand years of saltwater exposure.
The volcanic ashite d chemical reactions that made the material increasingly resistant to cracking.
Modern engineers study Roman concrete for insights into durable, sustainable construction.
