Examples

  • Several studies have shown that the impact resistance of concrete can increase with the addition of pozzolanic materials such as fly ash, slag, metakaolin, and silica fume.

    Academic text (2017)

  • The engineers selected several pozzolanic materials to enhance the durability of the concrete.

  • ECC mixtures were produced using different pozzolanic materials (PMs).

    Academic text (2016)

  • It has high pozzolanic activity and high alumina content compared to traditional mineral admixtures like fly ash and ground granulated blast-furnace slag.

    Academic text (2018)

  • Due to the combination of pozzolanic reaction, formation of additional carboaluminate, and improved chloride binding capacity by MK addition, chloride penetration is significantly restrained.

    Academic text (2018)

  • The synergistic effects of carboaluminate formed and the pozzolanic reaction of MK significantly increase compressive strength and obviously reduce the water-filled porosity when MK is incorporated.

Morphology

pozzolanic = pozzolan (opaque) = pozzolan + ic

The adjective is formed by regular suffixation of '-ic' to 'pozzolan', so the morphological relation is clear, but 'pozzolan' is a specialized technical term that many learners will not know.

Etymology

Pozzolanic comes from the Italian pozzolana, named after the town Pozzuoli, where builders used a special volcanic 'ash' long ago. That ash mixed with lime made a cement-like material, so pozzolanic describes materials that react with lime to form strong building material.
