Effect of three natural pozzolans in portland cement hydration
Materiales de Construccion, 2003 Natural pozzolans have been used since ancient times and continues to be used today. The chemistry and morphological composition of natural pozzolans and their particle size distribution allows classifying them as more or less reactive pozzolan.
