• Silica Sand an overview ScienceDirect Topics

    To make calcium silicate bricks, silica sand is mixed with high calcium lime at a sand–lime ratio of 10 or 20. The mix is then compressed into moulds and “autoclaved” at about 170°C (340°F) for several hours. Some gel, similar to the calcium silicate hydrate gel of the type that is formed by cement, is formed, and this bonds the sand particles together.

    ` The refractoriness of the silica sand is highest. Fineness ² ` Finer sand molds resists metal penetration and produces smooth casting surface. ` Fineness and permeability are in conflict with each other and hence they must be balanced for optimum results. Bench Life ² ` It is ability of the molding sand to retain its properties during storage.

    Silica sand is mainly used because of its thermal conductivity. It can absorb and transmit heat while allowing the gases generated during the thermal degradation of binders to pass through the grains. As a molding material, the sand is compacted and shaped according to the mold pattern that is going to be produced, as well as to create cavities.
