LD slag is a byproduct of steel industry, which comes from pig iron refining processing using LD converters. Because of its physical, chemical and mineralogical properties, it can be used as a substitute for aggregates in civil engineering projects. LD slag has the useful components like CaO, MgO with high basicities (CaO/SiO2) of above 3.0 ...

LD Slag is produced during the separation of molten Steel Slag from impurities in steel-making furnaces. Slag being a complex solution of silicates and oxides is lighter and hence, floats on top of the molten mass of steel. It is then tapped into a Slag pot which solidifies on cooling and is then separated.

Steel slag is similar to cement in their chemical and mineral composition, which has an excellent potential for application in the cement and concrete industry. However, the volume expansion caused by the high contents of f-MgO and f-CaO in steel slag limits its utilization rate (generally <10% w/w) in cement materials.
