摘要
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. (C) 2017 Elsevier Ltd. All rights reserved.
