AB Electric Arc Furnace (EAF) slag, a by-product of the steelmaking industry, also serves as a highquality aggregate material for structural concrete production. In this research, its use is proposedas a Dry-Shake Hardener (DSH), in substitution of quartz, in concrete paving top coatings. Threeconcrete paving slab kinds were produced using EAF: one without fibers, another with metallicfibers; and the third with synthetic fibers. Half of each slab was coated with a classical cementquartz mix and the other half with a novel cement-slag mix. After four years of outdoor agingat the city of Burgos, Spain, the slabs were visually inspected and no significant differences werefound between the two coated materials. Impact, skid, and abrasion resistance tests were carriedout and showed similar results for both types of coating courses. The result of both the short andlong-term water absorption test results indicated, firstly, no short-term water absorption in bothcases and, secondly, lower long-term water absorption in the quartz-cement mix. Finally,observation of the oil stain resistance tests on the top coatings led to the conclusion that thecleaning ability is very good. Analyzing all the results, it may be concluded that a new applicationfor EAF slag have been found, it is a suitable material for use as a DSH for coating concrete pavingslabs.
