National Pozzolan Association: The History of Natural

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.

Effect of Incorporation of Rice Husk Ash Instead of Cement

Rice Husk Ash to concrete improves the strength. However, when a low water/cement ratio is used, a weak performance is seen in Rice Husk Ash concrete (Giaccio et al.,2007;Vijai et al., ). Various research shows that mechanical and durability characteristics considerably improved with the incorporation of fibers (Ahmad et al.,2020a).
