In this paper the use of Electric Arc Furnace slag (EAF slag) for the production of High-Performances Concrete (HPC) is explored, as a fully replacement of the natural gravel. Several mixtures were produced, varying the water/cement ratio, the cement and the admixture content, with the aim of reaching a strength class between C50/60 and C60/75, and an S4 consistency class, as defined in EN 206-1. Mechanical properties of EAF concretes were compared with reference conglomerates; a complementary microstructural analysis was performed, with SEM observation after concrete specimens' failure. Results indicate that the use of EAF slag in concrete allows reaching higher compressive strength than with coarse natural aggregates. Lastly, the environmental benefits obtained through the use of recycled aggregates are shown, by means of the application of a Life Cycle Assessment (LCA) tool properly developed for this scope.

Abstract In this study the electric arc furnace slag was used as coarse natural aggregate substitute in concrete paving blocks production. The concrete mixture was defined by using weight proportions in the ratio of 1:2:3:0.51 (cement:sand:coarse aggregate:water) in order to obtain a compressive strength of 35 MPa. Four groups of concrete were prepared: a reference recipe and three others with the slag replacing the natural aggregate in the proportions of 25%, 50% and 75%. The compressive strength was not influenced by the slag content; however, it was influenced by the curing age, as the sample with 75% of slag addition had its compressive strength increased by 13.5% from 7 to 56 days. Water absorption presented a slightly reduction with slag addition. The results of compressive strength and water absorption met the Brazilian technical requirements, making the paving blocks suitable for use in light vehicle traffic. The results obtained in this study highlight the influence of the production process in the final quality of the steel slag, and the need of stablishing technical and environmental requirements to guide and promote the safe use of electric arc furnace slag in concrete.
