ABSTRACT
The current paper reports on corrosion behavior of steel bar embedded in slag-cement paste under coupled chloride and sulphate attack. Electrochemical study, particularly Tafel Polarization method, was considered to investigate the corrosion resistance of steel bar in hardened slag-cement immersed in 3.5%NaCl+5%Na2SO4 in a static corrosion environment. Three types of specimens with 0%, 20% and 40% slag content as a supplementary cementitious material (SCM) were used. The experiment was executed within 270 days in an ambient temperature. The results showed that the sample S2-LB3 with 20% slag has the most corrosion resistance after 270 days under chloride and sulphate attack.
