Corrosion behavior of reinforcement bars embedded in mortar specimens containing ladle furnace slag in partial substitution of aggregate and cement

► Corrosion potentials decrease with the increase of humidity and the chloride ions. ► The increase in the humidity content, produces the increase in corrosion rate. ► Mortars with 0% and 0.4% chloride ions, reach corrosion rates for passive state. ► Mortars with 0.8%, 1.2% and 2% chloride ions, reach corrosion rate for active states. ► Mortars of reference and with LFS in presence of chlorides, behave in a similar way.
