Artificial pozzolana from silica gel waste–clay–limestone …

 · It was estimated that combustion of silica gel–clay–limestone composite at 700 C produced a new artificial pozzolana (SGCL), the pozzolanic activity of which is 260 mgCaO/g. During the combustion process, the fluorine from silica gel was not released into the atmosphere, but combined to form a stable CaF 2 compound.
