Abstract
The use of oxidizing slag from electric-arc furnaces as an aggregate is a sustainable option in the
manufacture of concrete, the performance of which is similar to an ordinary aggregate concrete. This
study examines the reuse of two different types of oxidizing slag in concretes designed for use in structural
components and compares their performance against relevant specifications contained in current
working standards. Fundamental aspects are discussed, among which density and workability that are
related to the proportioning of the concrete and its mechanical and physical properties. The results show
that overall concrete quality is maintained and that its performance is acceptable for the proposed
application
