After the clinker is cooled, cement plants grind it and mix it with small amounts of gypsum and limestone. Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects.

Steelmaking slag is an integral part of the steelmaking process. It is produced during the separation of the liquid steel from impurities in steelmaking furnace and is a non-metallic by-product of steelmaking process. It occurs as a molten liquid melt and is a complex solution of silicates and oxides which solidifies upon cooling.

Ostrava, 2 October 2019 – The Liberty Steel mill will deliver 150,000 tonnes of blast furnace slag, so called slag aggregate, a by-product of the hot metal production, for the construction of a bypass road in Frýdek-Místek. Using blast furnace slag saves consumption of natural stone. It is a high-quality material suitable for the base layer of roads.

BBOF slag (BOFS) is produced in the steelmaking process by using the molten iron coming from the BF. In the second method, slags are generated in the scrap-based steel industry. The first stage of the scrap-based steel industry production generates EAF slag (EAFS) and a second stage is performed to refine the molten steel.
