In brief
By studying ancient techniques, scientists explore solutions to reduce carbon emissions in construction.
In a fascinating intersection of history and innovation, the Italian Ministry of Culture has made waves with the discovery of a new room in the ruins of Pompeii this past June. Amongst the vibrant frescoes and luxurious blue paint characteristic of the Roman elite, a seemingly mundane pile of granular sandy material caught the eye of M.I.T. chemist Admir Masic. This unassuming substance, he explained, is a precursor to the ancient Roman concrete that supported vast infrastructure across the empire, from aqueducts to monumental buildings.The exceptional longevity and resilience of Roman concrete starkly contrasts with modern Portland cement, which, despite its prevalence and affordability, is prone to cracking and has a detrimental impact on our planet. Concrete production contributes significantly to global carbon dioxide emissions, accounting for approximately 8 percent of the total. Researchers like Masic are increasingly turning to historical materials to find alternative methods that could enhance the longevity of modern construction while addressing environmental concerns.“Roman marine concretes have survived in one of the most aggressive environments on Earth with no maintenance at all,” notes geologist Marie Jackson from the University of Utah. This resilience offers a compelling blueprint for future building practices, inspiring innovators to harness ancient knowledge in the quest for sustainable construction solutions. By incorporating the age-old secrets of Roman cement, there’s hope for creating new, eco-friendly materials that not only stand the test of time but also contribute to a greener future.
