Adding pozzolans to an existing concrete mix without removing an equivalent amount of cement increases the paste content and decreases the water/cement ratio. In other words, adding more pozzolans to a mix changes the mix proportions. Replacing some of the cement with pozzolans preserves the mix proportions.

Pozzolana

The pozzolanic reaction is the chemical reaction that occurs in portland cement containing pozzolans. It is the main reaction involved in the Roman concrete invented in Ancient Rome. At the basis of the pozzolanic reaction stands a simple acid-base reaction between calcium hydroxide (as Portlandite) and silicic acid.

Hydration of the cement–pozzolana blend is generally more gradual than that of a pure cement, although the filler effect can lead to an ever-so-slight acceleration of early age hydration. The pozzolanic reaction also leads to a lower heat evolution during hydration and a reduction in the portlandite content, with increased production of C-S-H (with implications for durability).
