Spent foundry sand consists primarily of silica sand coated with a thin film of burnt carbon residual binder (bentonite sea coal resins) and dust. Table 7-2 lists the chemical composition of a typical sample of spent foundry sand as determined by x-ray fluorescence. Silica sand is hydrophilic and consequently attracts water to its surface.

This work investigated the effects of Bentonite and Cassava starch binders on foundry moulding sand. The two binders were applied separately to silica sand in different proportions and also as a mixture in different proportions as well. The effects of these various additions on foundry moulding sand were investigated by conducting out various tests as permeability, moisture content, green ...
` 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.
