Pozzolanic activity of kaolins containing aluminum hydroxide. [PDF]
Sci Rep, 2020 AbstractThe addition of 10 wt% aluminum hydroxide to two crude kaolinitic clays, a commercial and a natural freshly mined one, has enhanced their pozzolanic activity, more substantially in the natural sample containing gibbsite. The obtained blends were used as replacement of 20 wt% of Portland cement in the formulations of pastes and mortars which ...

The Pozzolanic Activity of Calcined Clay – Silica Gel Composites
Medžiagotyra, 2013 The effect of silica gel additive on pozzolanic activity of burned clays was investigated on this study. It was determined that calcined (600 ºC – 730 ºC) clay of Saltiskiai quarry has very low pozzolanic activity (104 mg – 55 mg CaO/g).

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.
