Waste foundry sand is used as a fine aggregate and Steel slag is used as a coarse aggregate Waste Foundry Sand (WFS) Metal industries use sand casting in which moulds are made of uniform sized, clean, high silica sand. After the casting, process foundries recycle and reuse the sand several times but after some time, it is discarded from the foundries known as waste foundry sand. Its ...
Waste Foundry Sand in Asphalt Concrete
Waste foundry sand (WFS) is a byproduct of the casting industry that results from the molding and coremaking processes. The mold forms the outside of the castings, and the core forms the internal shape. When the part to be made has deep recesses or hollow portions, sand cores must be provided in the mold. The annual generation of WFS in Indiana is about 1. 78 MN (200,000 tons) (1). The bulk ...
