Effects of the secondary minerals of the natural pozzolans on their pozzolanic activity
Cement and Concrete Research, 2008 Abstract Natural pozzolans have been widely used as substitutes for Portland cement, because of their binding properties. Some of them are natural volcanic rocks which contain secondary minerals such as clays and zeolites corresponding to products of the alteration of the rock.
