Of these, silica fume is the most reactive, with metakaolin being close to silica fume in terms of reactivity. Fly ash is less reactive, especially during the first few days of curing when less calcium hydroxide is generated. Generally the finer the pozzolan particles are, the more reactive they are. Silica fume is the finest with most particles averaging 0.3 Âµm (microns), metakaolin averages about 4 Âµm, Portland cement averages about 15 Âµm, and fly ash about 70 Âµm. Many pozzolans are waste products from industrial processes.
