Blastfurnace slag is obtained as a by-product from iron making industry, it is then dried and ground into a fine powder. After that the powder is ready to be used for production of blastfurnace cement. Cement with admixture of blastfurnace slag possesses significantly improved properties such as durability, strength, lower permeability, lower hydration, more resistance to aggressive chemicals and it has proven to reduce costs for cement production.

Blastfurnace cement has several advantages in respect to the environment. Firstly, it reduces CO2 and other toxic emissions, saves natural resources and reflects more sun energy, thus limiting the heat island effect.

Concrete made with blastfurnace cement can be used for the same purposes as normal Portland cement is usually used for. CEM III/A 42.5 N is applicable for all types of concrete.

With its special properties it is suitable for extreme conditions, especially for construction of large projects as bridges, dams, roads, tunnels, see walls, ports, geo thermal facilities and others. Primarily it is preferred in the hot weather conditions due to low hydration and high resistance to sulfate and acid attack.
