An Enduring Formula
Roman concrete, or opus caementicium, has amazed scientists and engineers for its durability. Structures like the Pantheon and aqueducts, built over 2,000 years ago, still stand, defying the wear of time and natural elements.
Unique Ingredients
The Romans mixed volcanic ash, lime, and seawater to create a highly durable concrete. When combined, these materials triggered a chemical reaction, forming tobermorite crystals, which strengthen over time, especially in seawater.
Rediscovered Strength
In 2017, researchers discovered that Roman concrete’s self-healing properties came from the volcanic ash reacting with water to fill cracks. This made it particularly useful for harbor structures that remain intact despite centuries of wave action.
A Modern Inspiration
Scientists study Roman concrete to replicate its composition, aiming to develop sustainable, long-lasting building materials. Despite advancements, the precise replication of this ancient recipe remains a challenge for modern engineers.
