Ladle furnace slag is a by-product of carbon steel manufacturing produced during the second stage of steelmaking in the ladles where the chemical composition of steel is adjusted prior to casting of steel semi-finished products. The slag produced in the ladle has a high content of calcium (around 40%) due to addition of calcium-containing fluxes.

Blast Furnace Slag Cement is acquired as a by-product when the iron is extracted from its ores. The process by which iron is extracted is executed with the help of a blast furnace. Meanwhile, the acquired slag from the ore is then segregated before letting them cool down gradually. This leads to the creation of unreactive crystalline elements.
