Resumen
The manufacture of concrete with Electric Arc Furnace slag as aggregate is known; in this work, fiber reinforcements are added to this concrete. The properties of several mixes, reinforced with 0.6% metallic and 0.4% synthetic fibers in volume, are studied both in the fresh and in the hardened state. Mechanical characterization of the fiber-reinforced concretes showed that they had good compression, flexural and tensile splitting strength. They also showed good toughness, post-cracking behavior, impact strength and tests on their abrasion resistance yielded suitable results. The concrete mixtures were characterized with SEM, to analyze their microstructure and the adherence of fibers. © 2017 Elsevier Ltd
