STEEL SLAG AS AGGREGATE
We continue to bet on the circular economy using waste from other industries in paving
The most important steel mill in Uruguay, Gerdau-Laisa, generates around 10,000 tons of slag per year that ended up being buried in a landfill. With the approval of Dinama for use in road construction, it is possible to use a very valuable residue with good properties for surface treatments.
The material has excellent shape and high wear resistance in both the Los Angeles and Microdeval tests. The granulometries achieved fit very well with those we propose in the Book "High Performance Surface Treatments" achieving ranges of 2-6mm, 6-10mm, 10-14mm and 14-20mm. In terms of adhesion by Vialit plate, it exceeds 90%, complying with what is required.
The quality of the treatments carried out depends largely on the possibility of having resistant, cubic and well classified aggregates as is the case with this material. We leave you some photographs of the section made where you can see the quality of the aggregate used. We continue to take steps on the circular economy and caring for the environment in all our products and related techniques.
