· The present investigation focuses on the development of metal casting mold using stonedust as an alternative mold material to silica sand. The stonedust aggregate mold having 4 wt.% of moisture and 11 wt.% of bentonite clay shows desired mold properties as per AFS standard. The mold properties such as permeability number, hardness (Bscale), compressive, and shear strength are .
Silica (industrial) sands contain a high proportion of silica (normally, but not exclusively, more than 95% SiO2). It is recognised by government as an essential raw material of national importance and as such there is a requirement to provide an adequate and steady supply, through maintaining stocks of permitted reserves and safeguarding silica sand resources.
· Not all sand is silica sand. Beach, riverbed and similarly situated sand deposits are not used in the glass container industry. Silica sand appropriate for remelting in glass furnaces needs to meet detailed industry specifiions and is not found in beach or riverbed areas, but in specific mineral deposits with proven multiyear reserves and properly reforested at the end of their useful life.
