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).

Super rapid removal of copper, cadmium and lead ions from water by NTA-silica gel

RSC Advances, 2018
Copper (Cu2+), cadmium (Cd2+) and lead ions (Pb2+) are toxic to human beings and other organisms. In this study, a silica gel material modified with nitrilotriacetic acid (NTA-silica gel) was sensibly designed and prepared via a simple amidation ...
