Foundry sand consists primarily of silica sand (>80% silcon dioxide), coated with a thin film of burnt carbon and residual binder (Du et al 2002). Loss on ignition in foundry sand has been reported by the American Foundrymen's Association (1991) to be around 5%. Depending on the binder and type of metal being cast, the pH of foundry sand can

· In an effort to extend the reutilization of waste foundry sand (WFS), we evaluated the use of WFS as a replacement for clay in tile manufacturing. The effects of WFS addition on the properties of clay tile specimens were investigated at six different levels of WFS replacement: 0, 10, 15, 20, 40, and 60%. These specimens were fired at one of three different kiln temperatures: 1,000, 1,050, and ...

State regulations of foundry sand reuse are guided by the concept of ensuring the protection of human health and the environment. Rules guiding foundry sand reuse vary from state to state. Some states have a single set of requirements for all industrial byproducts, while others have rules specifically guiding the reuse of foundry sand.

foundries' sand to find its reuse possibility in composting: the composting experiment showed that surplus foundry sand that would have been dumped in landfill contains fluoride, phenol and BTEX. These harmful components disappear during composting. This shows that reuse of surplus foundry sand does not adversely affect the environment.

reuse foundry sand and other solid wastes. Indiana statute allows for specific reuse of type III foundry sand without having to get a permit from IDEM (IC 131937). Indiana's Solid Waste Rule (329 IAC 1031) allows for other uses of spent foundry sand and other solid waste when the reuse is determined to be "legitimate." Foundries and the metal casting industry generate spent foundry ...
