Abstract: The highly durable pozzolanic mortars of wall concretes from the Theater of Marcellus and Great Hall of Trajan’s Markets preserve traces of micromorphological textures in altered Pozzolane Rosse volcanic ash. Reaction of hydrated lime with potassic scoriaeceous ash, and halloysite, phillipsite, and chabazite surface coatings, as well as Tufo Lionato tuff particles, produced distinct, alkali- and alumina-calcium-silica hydrate cement microstructures, including strätlingite. The assemblage of diverse pozzolanic components in the Trajanic mortar was remarkably effective in combining hydrated lime.
