Silica sand, also known as quartz sand, white sand, or industrial sand, is made up of two main elements: silica and oxygen. Specifically, silica sand is made up of silicon dioxide (SiO2). The most common form of SiO2 is quartz - a chemically inert and relatively hard mineral. SiO2 grades at a 7 out of 10 on Mohs hardness scale, making it ...

Mar 23, 2022The by-product of the foundry industry is waste foundry sand (WFS). The use of WFS in building materials will safeguard the ecosystem and environmental assets while also durable construction. The use of industrial waste in concrete offsets a shortage of environmental sources, solves the waste dumping trouble and provides another method of protecting the environment.

Foundry industries generally recycle and reuse the used foundry sand many times in casting process. When the sand can no longer be reused in the foundry, it is removed from the foundry and is termed as "foundry waste sand."
