Ecocement, which is a new type of hydraulic cement made from the incineratedashes, contains large amounts of chlorides. Therefore, when this type of cement is applied to reinforced concrete structures, .there is a risk of steel bar corrosion. In this study, the effect of the water to cement ratio and the replacement percentage of blastfurnace slag on the corrosion of steel bars embedded in ecocement-slag mortars under a severe saline environment was investigated. It was found that both the low water to binder ratio and the addition of slag could improve the corrosive behavior of steel bars embedded in the resulting mortars.
