Corrosion behavior of duplex stainless steel reinforcement in ternary binder concrete exposed to natural chloride penetration

The corrosion behavior duplex stainless steel rebars embedded in concrete exposed to natural chloride penetration has been carried out. Three duplex stainless steels (DSSs) differentiated in the Ni, Mo and Mn content and two types of concretes elaborated with different binders, Portland cement and Portland cement blended with Slag and Limestone, were employed. The corrosion behavior was followed through Ecorr and Rp measurements along the...
