Roman concrete derives from a type of volcanic ash called Pozzolana. Unlike other types of volcanic material, Pozzolana contains siliceous (silicon dioxide) and aluminous elements. This unique composition makes the ash react with other materials. Under the right conditions, this ash will bond with specific elements to create a type of cement.
