Pozzolana
Pozzolana, also known as pozzolanic ash, is a fine, sandy volcanic ash, originally discovered and dug in Italy at Pozzuoli in the region around Vesuvius, but later at a number of other sites.Vitruvius speaks of four types of pozzolana. It is found in all the volcanic areas of Italy in various colours: black, white, grey and red.

Pozzolana
The pozzolana as shown in Fig. 18.2 A containing active silica, when mixed and ground with lime, produces strong mortar and sets to give quite hard products, like cement mortar, on reaction with water. Italian pozzolana is known throughout the world and the ancient buildings of Rome used this pozzolana.
Pozzolana vs. Pozzolan — What's the Difference?
Pozzolana is noted for its role in creating the hydraulic cements of ancient Roman architecture, improving durability and water resistance. On the other hand, pozzolan includes materials like fly ash and silica fume, which are by-products of industrial processes and also enhance modern concrete.
