    摘要: PURPOSE:To enlarge particle size of sand, to improve water permeability of sand and to extremely shorten drying time without reducing strength of sand by coating the surface of sand with a silicate compound and then baking. CONSTITUTION:The surface of sand is coated with a silicate compound and the sand is baked. A solution of glaze used in the production of ceramics is used as the silicate compound, attached (dipping or spraying method) to the surface of sand and baked. The baking, for example, is carried out by using a rotary furnace and heating at about 1,000 deg.C.
