摘要: Abstract The present paper aims to investigate the passivation capability and accelerated chloride-induced corrosion behaviour of a novel alloy steel (00Cr10MoV) conventional low-carbon (20MnSiV) in ordinary Portland cement (OPC) alkali-activated slag (AAS) mortars. Both steels were embedded mortars with intact mill scale. Compared OPC mortar, AAS mortar resulted formation less protective passive film for both 20MnSiV 00Cr10MoV after due presence reducing sulphides. Despite this, initial negative effect on can be well compensated by its denser interfacial microstructure occurrence active induced chlorides. As however, this compensating was pronounced. Moreover, unexpected low resistance confirmed defective Cr-depleted
