Calcium hydroxide (lime) accounts for up to 25% of the hydrated Portland cement but it does not contribute to the concrete's strength or durability. Pozzolans combine with the lime ...

The cement/concrete industries soon transitioned from natural pozzolans to coal combustion residuals (fly ash) as their pozzolans of choice due to cost and availability. Artificial pozzolans, being a waste material, were happily given away or sold at a minimum cost. That dynamic has changed. Fly ash—in particular Class F fly ash—has played ...

Aug 11, 2022Note 1: Finely divided materials may tend to reduce the entrained air content of concrete. Hence, if a fly ash or natural pozzolan is added to any concrete for which entrainment of air is specified, provision should be made to ensure that the specified air content is maintained by air content tests and by use of additional air-entraining admixture or use of an air-entraining admixture in ...

The benefits of pozzolan use in cement and concrete are threefold. First is the economic gain obtained by replacing a substantial part of the Portland cement by cheaper natural pozzolans or industrial by-products. Second is the lowering of the blended cement environmental cost associated with the greenhouse gases emitted during Portland cement production. A third advantage is the increased ...
