Portland pozzolana cement is a blend of portland cement and pozzolana. Pozzolana is a volcanic ash that contains silica and alumina. When used in Portland pozzolanic cement, the pozzolan reacts with the lime in the portland cement to form a gel that binds the aggregates together. The result is a very strong mortar or concrete. Artificial Pozzolana:
