Slag aggregate

The slag aggregate comes from the treatment of slag generated during the steelmaking process in our electric arc furnace steelworks.

Mainly used as aggregate for structural and non-structural concretes, concrete pavements, bituminous mixtures in road layers, surface treatments of road surfaces, granular bases and sub-bases of road surfaces, embankments and ramparts, ditch fillings, of urbanization and beyond of retaining walls and abutments of bridges, among others.

To guarantee the volumetric stability, the quality and size of the resulting steel aggregates suitable for their different applications, the following treatments are mainly carried out: cooling and stabilization of compounds, crushing, deferretization, screening, storing and characterization of the product.
