AB  - Electric-arc furnace slag is proposed as a substitute for the conventional aggregate used in classical structural
concrete. In the present research is studied the durability of these slag aggregate concretes and their
resistance to both physical (freeze–thaw, high temperature and relative humidity) and chemical degradation
(sulfate attack, alkali–aggregate reaction and marine environment), as well as their resistance
to the corrosion of steel reinforcement bars (an assessment of the risks of corrosion) embedded in the
concrete matrix. This approach requires laboratory studies. The main objective of this work focuses on
evaluating the durability of slag concrete under the conditions specified in the Spanish structural
concrete code. In general terms, the behavior of the concrete with slag aggregate was similar to or better
than the reference concrete (natural aggregate), except in case of exposure to marine environments and
seawater, which resulted in quicker chloride penetration. The study confirms the viability of producing
steel-reinforced concrete with slag aggregate.
