Reactivity and expansion of electric arc furnace slag in their application in construction
EAF-slag have adequate technical properties for its use as aggregates. The MgO content is the main responsable of the expansions. The expansion produced affect in different way the new material depending of the rigidity of the matrices formed. EAF-slag shows hidraulicity and forms as reaction produc...
