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

摘要

Corrosion will inevitably affect steel reinforcement bars embedded in mortar specimens. In this study, we examine the corrosion of rebars embedded in mortar made with Ladle Furnace Slag (LFS), in partial substitution of aggregate and cement. Prismatic specimens measuring 6×8×2 cm~3 were prepared with variable amounts of chloride ions. Subsequently, their behavior in the presence of steel corrosion was analyzed by electrochemical techniques. Our analysis of the results concludes that rebar behavior in the LFS specimens is similar to rebar behavior in the conventional mortars that were used as the reference specimens.
