Slag products

Old but effective

For many decades, high-quality construction materials have been manufactured in Linz from slags obtained from the blast furnace and steelmaking processes. Whether quickly cooled with water (metallurgical slag) or cooled slowly (lump slag), these are secondary raw materials in sectors such as the cement, insulation and road construction industries. Material recycling processes contribute significantly to the conservation of natural resources and environmental protection.

Granulated blast furnace slag

Metallurgical slag is a valuable additive in cement making. Its use yields substantial benefits: Conservation of natural resources, reduction of CO2 through reduced use of clinkers and energy savings

This material also shows its strengths as a quartz-free sand in corrosion protection.

Blast furnace lump slag

Blast furnace lump slag is used in civil engineering, particularly in road construction. Product advantages also include volume stability, high load capacities, angular grain shapes and low bulk density.

Metallurgical slag

Metallurgical slag is among the hardest stones used in road construction. Because of its enormous resistance to abrasion and excellent grip characteristics, metallurgical slag is used in wear-resistant asphalt surface layers. It is also used as an additive in cement making.

Pouring ladle slag

Is used as an additive in the blast furnace. Als Kalzium- und aluminiumhaltiger Rohstoff wird diese für die Zementindustrie und die Steinwolleerzeugung verwendet. Pouring ladle slag is also used in agriculture as a lime fertilizer.
