The Pozzolanic Activity of Calcined Clay – Silica Gel Composites

open access: yesMedžiagotyra, 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).
