Durability studies on fiber-reinforced EAF slag concrete for pavements

The long-term behavior of fiber-reinforced hydraulic concretes for pavement applications is studied in this paper. These concretes are manufactured with Electric Arc Furnace Slag as aggregate and exposed to aggressive environments. Mechanical properties, porosity, capillary structure, and long-term variations in length are measured in compressive, tensile, Mercury Intrusion Porosimetry, Fagerlund, and shrinkage tests. The concrete samples are subjected to conventional durability - freeze/thaw and moist-dry - tests and exposed to aggressive agents as sulfates, carbon dioxide, and sulfidic atmospheres with good results. Finally, a set of concrete slabs prepared outdoors are successfully left to weather under detrimental conditions. (C) 2017 Elsevier Ltd. All rights reserved.
