Silica and Moulding Sands Association (SAMSA) part

About 11% of the sand sold in 2004 was used for foundry purposes. Foundry moulds are mostly made from a mixture of silica sand chemically bonded with i.e.Phenolics or Furanes etc. : bentonite and water. Much of this material is now recycled for reuse. Spent foundry sand is also used as asphalt filler and in concrete manufacture.
