Sodium silicate bonded sand Sodium silicate is a water soluble glass available from suppliers in a wide range of types specified by the silica (SiO2), soda (Na20) and water content. Manufacturer's data sheets specify the 'weight ratio' of silica to soda, the percentage of water and the viscosity.

Sodium Silicate Study Bench

Reclamation by Drying and Secondary Attrition By the late 70's, early 80's, another form of reclaiming silicate-bonded sands became popular which relied on 'drying' of the sand after primary attrition to de-hydrate the binder and thus making it brittle. A secondary attrition cell was then used to impart 'work' or 'energy' in various
