Apr 26, 2020· Slag cement, often called ground granulated blast-furnace slag (GGBFS), is one of the most consistent cementitious materials used in concrete. It is actually a byproduct of iron production. When the iron is processed using a blast furnace, slag and iron both collect at the bottom of the furnace.

Production and composition. The chemical composition of a slag varies considerably depending on the composition of the raw materials in the iron production process. Silicate and aluminate impurities from the ore and coke are combined in the blast furnace with a flux which lowers the viscosity of the slag. In the case of pig iron production the flux consists mostly of a mixture of limestone and

Slag is a non-metallic by-product of the steel-making process sourced from blast-furnaces which is mostly used to make iron. It is converted to granulated blast furnace slag (GBFS) by quickly cooling molten slag with industrial water or steam. Granulated Blast Furnace Slag has a glassy structure and can be used as a fine aggregate or binder.
