6 . Ancient builders across the world created structures that are still standing today, thousands of years later. Yet the concrete that makes up much of our modern world has a lifespan of around 50 to 100 years. A growing number of scientists have been studying materials from long-ago eras, hoping to uncover how they’ve held up for millennia.
Many researchers have turned to the Romans for inspiration. Starting around 200 BCE, the architects of the Roman Empire were building impressive concrete structures that have stood the test of time. Even in harbors, where seawater has been battering structures for ages, you’ll find concrete basically the way it was when it was poured 2,000 years ago. Most modern concrete starts with Portland cement, a powder made by heating limestone and clay to super-high temperatures and crushing them. That cement is mixed with water to create a chemically reactive paste. Then, blocks of material like rock and gravel are added, and the cement paste mixes them into a concrete mass. According to records from ancient architects, the Roman process was similar. The ancient builders mixed materials like burnt limestone and volcanic sand with water and gravel, creating chemical reactions to stick everything together.
In a study published earlier this year, Admir Masic, a civil and environmental engineer, proposed that this power comes from blocks of lime that are scattered throughout the Roman material instead of being mixed in evenly. Researchers used to think these blocks were a sign that the Romans weren’t mixing up their materials well enough. Instead, after analyzing concrete samples from Privernum—an ancient city outside of Rome — the scientists found that the blocks could fuel the material’s “self-healing” abilities. When cracks form, water is able to flow into the concrete, Masic explained. That water activates the leftover lime, leading to new chemical reactions that can fill in the damaged sections.
The ancient architectures suggested using extracts from local chukum and jiote trees in the lime mix. When researchers tested out the recipe, they found the resulting plaster was especially durable against physical and chemical damage.
Studies have found all kinds of natural materials mixed into structures from long ago: fruit extracts, milk, cheese curd, beer, even dung and urine. The paste that holds together some of China’s most famous structures—including the Great Wall and the Forbidden City — includes traces of sticky rice.
“Some of these ancient builders might have just gotten lucky”, said Cecilia Pesce, a materials scientist at the University of Sheffield in England, “They’d throw just about anything into their mixes, as long as it was cheap and available.”
Today’s builders can’t just copy the ancient recipes. Even though Roman concrete lasted a longtime, it couldn’t hold up heavy loads: “You couldn’t build a modern skyscraper with Roman concrete,” Cecilia said. “It would collapse.” Instead, researchers are trying to take some of the ancient material’s specialties and add them into modern mixes.
