Roman architectural mortar, by contrast, is a mixture of about 85 percent (by volume) volcanic ash, fresh water and lime, which is calcined at much lower temperature than Portland cement. Coarse chunks of volcanic tuff and brick compose about 45 to 55 percent (by volume) of the concrete. The result is a significant reduction in carbon emissions.
