Steel is much more susceptible than iron to shrink stresses, and in some situations, these tensions can lead to significant internal and/or external voids, and possible eventual fractures. For these reasons, cast steel requires more attention and inspection throughout the casting process, making production more resource intensive. Machinability

Silica has a high melting point, making it an ideal product for use in foundries. An item pressed into the sand leaves an imprint, which the foundry fills with molten metal. Once the cast has hardened, workers lift it from the sand mold and brush away any remaining sand. The relatively small granule size of silica sand is also ideal for filtration.
Corrosion is the chemical reaction where metals break down slowly because of other elements in their environment..Rusting, a well known example of corrosion, is the breakdown of the metal reactants of this chemical reaction are iron, water, and oxygen, and the product is hydrated iron oxide, better known as, unlike iron, is crumbly, orange, and pretty much useless for ...

Sand (primarily silica) is used in construction as a component in various materials like concrete, mortar etc. Definitely the salts adsorbed (dissolution might not actually occur) on sand are going to affect the durability in reinforced concrete structures but in plain concrete or mortar for plaster, it might not be that detrimental. It is not that hard to get rid of salts adhered to sand ...
