Silica Sand uses

Moulding Sand: Most moulding sand casting operations use Silica sand (SiO2). Usually, sand used to manufacture a mould for the casting process is held together by a mixture of water and clay. A typical mixture by volume could be 89% sand, 4% water, 7% clay. Control of all aspects of the properties of sand is crucial when manufacturing parts by sand casting. Molding Sand Constituents and Composition Molding sand is composed mostly of silica sand, a binder, moisture content, and additives, among other things.
