Valorisation des laitiers d'aciérie de conversion dans les liants hydrauliques routiers

Abstract : Basic Oxygen Furnace slag (BOF slag) valorisation in hydraulic road binders is investigated. The study was conducted on two different aspects. In a first part, BOF slag characterization, their hydraulic behaviour analysis and their thermal and/or chemical activation study were presented. They have interesting compressive strength (50Mpa) at 180 days. The particle size distribution, temperature and CaCl2 improve BOF slag mechanical properties. An industrial study has focused on BOF slag based hydraulic road binders formulation. Their mechanical properties have been studied according to standardization. It results that the use of 30 to 40% of BOF slag in hydraulic road binders is possible. This conclusion represents an attractive solution to enhance these industrial byproducts
