Ground granulated blast furnace slag (GGBS or GGBFS) is obtained by quenching molten iron Iron is a metallic chemical element with the symbol Fe (Latin: ferrum) and atomic number 26. Iron is a group 8 and period 4 element and is therefore classified as a transition metal. Iron and iron alloys (steels) are by far the most common metals and the most common ferromagnetic materials in everyday use. Fresh iron surfaces are lustrous and slag Slag is a partially vitreous by-product of smelting ore to separate the metal fraction from the worthless fraction. It can be considered to be a mixture of metal oxides; however, slags can contain metal sulfides and metal atoms in the elemental form. While slags are generally used as a waste removal mechanism in metal smelting, they can also serve (a by-product of iron and steel Steel is an alloy consisting mostly of iron, with a carbon content between 0.2% and 2.1% by weight, depending on the grade. Carbon is the most cost-effective alloying material for iron, but various other alloying elements are used such as manganese, chromium, vanadium, and tungsten. Carbon and other elements act as a hardening agent, preventing making) from a blast furnace A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally iron in water or steam, to produce a glassy Vitreous or glassy refers to a material in an amorphous state , thereby forming a glass. In such a state, the constituent atoms do not exhibit the long-range order that is characteristic of crystals. However, they still exhibit short-range order -- the separation of atoms and/or the lengths of covalent bonds are very close to their typical, granular product that is then dried and ground into a fine powder.
