The Pozzolanic Activity of Calcined Clay – Silica Gel Composites [PDF]
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).

Enhancement of the pozzolanic activity of natural clays by mechanochemical activation
Construction and Building Materials, 2022 Replacement of cement with supplementary cementitious materials (SCMs) is a proven method to reduce clinker in cement and contribute to decreased CO2 emissions. Natural clays are commonly occurring materials that do not possess pozzolanic activity in their original state.

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 ...

Monitoring pozzolanic activity by direct activation with calcium hydroxide
Construction and Building Materials, 1996 Abstract In this paper the change in conductivity of pozzolan/CH mixtures, at ambient temperatures, is monitored for periods extending over two days. Such a method allows the chemical activity within the mixture to be followed and it is shown that a number of features/parameters can be identified which are related to the pozzolanic reactivity of the ...
