New Studies of Ancient Concrete Could Teach Us to Do as the Romans Did
Berkeley Lab, UC Berkeley experiments show how natural chemistry strengthened ancient concrete
A new look inside 2,000-year-old concrete – made from volcanic ash, lime (the product of baked limestone), and seawater – has provided new clues to the evolving chemistry and mineral cements that allow ancient harbor structures to withstand the test of time. The research has also inspired a hunt for the original recipe so that modern concrete manufacturers can do as the Romans did. (more…)
