201311;Both pozzolans were volcanic ashes or pumicites with high volcanic glassy form. The Romans and Greeks used natural pozzolan-lime mixture as binding materials for many structures over 2000 years ago. Such mortars consist of six parts of a natural pozzolan, two parts by volume of lime, and one part by volume of sand.
