Slag Management
Our products:
LiDonit® is a synthetic mineral created from the calcium silicate-rich converter slag in accordance with the Linz-Donawitz steel manufacturing process. Silicates and pure oxygen are specifically added to the slag when it is still in liquid form. This unique liquid slag treatment reduces the free lime content and ensures the lasting stability of this product.
What are the special features of LiDonit®?
High PSV values and good bitumen affinity make LiDonit® an excellent mineral for asphalt production. Our 5/8 mm grain size is preferred for producing the top layer made of open-pored asphalt.
The cubic grain shape ensures outstanding stability and water permeability when used as a bedding grain for laying paved footpaths.
The rough surface produces a permanently high grip when used in top layers. The prerequisite for the successful use of LiDonit® in road construction is its high strength coupled with low impact fragmentation values.
Regular external monitoring and our in-plant production control system guarantee the uniform quality of this product.
PSV value PSV57
Grain shape SI15
Impact fragmentation value SZ18
Eolit® is a high-quality product that we obtain from electric furnace slag at our production sites in Brandenburg a. d. Havel and Hennigsdorf. We produce chippings, mixtures, and gravel as well as armourstones according to demand.
What are the special features of Eolit®?
High PSV values and good bitumen affinity make Eolit® an excellent mineral for asphalt production. Our 5/8 mm grain size is preferred for producing the top layer.
As a regularly monitored additive for asphalt production, Eolit® is also popular as a paving bedding material in garden and landscape construction and for industrial sites.
We can also use standardized qualities for hydraulic engineering (embankment and drainage construction) applications from our production sites in Brandenburg a. d. Havel.
Monitored slag mixtures from both locations round off the range of qualities available for use as loose base and frost-protection layers.
The products we offer are all made in accordance with the given standards, which still leaves us sufficient flexibility to implement customer-specific concepts.

BaseLith® is a mineral mixture gained from steel production in accordance with the Linz-Donawitz process.
This product is characterized by its versatile range of applications in open construction. High load-bearing and compressive strength and a stable grain filter dependent on the grain size ensure excellent drainage.
BaseLith® is available in grain sizes from 0 to 63 mm, depending on the application. We also offer non-standard grain sizes on request.
BaseLith® is mainly used for constructing forestry roads and paths, for parking areas in landscape and outdoor applications, for stabilizing the substrate in equestrian and sports facilities construction, and also for embankments and filling harbor basins.
Just like other slag products, our BaseLith® is regularly inspected by an independent, accredited testing authority as well as for conformity with the required specifications. It does not contaminate water and is even suitable for applications up to German Water Protection Area III when used below loose top layers.
